3. Write short notes on.

Question 1.
Factors affecting regional development.
Answer:
The physical factors like relief, climate, location, population and land use of the region affects the regional development.

Regional development occurs near areas with favourable location, plain relief, sufficient rainfall, developed agriculture, transportation, industries and trade. For example, Asian countries have developed agriculture and trade of agricultural goods. USA has developed industries and trade.

There is poor development of economic activities in areas with unfavourable relief like mountains or hills and extreme climate. For example, in the northern part of Russia, economic development is poor due to extreme cold climate.

Location of the region is an important factor. If there is a long and broken coastline, then there is development of ports and thus development of trade and economy. For example, Japan has economically developed in spite of limited natural resources, due to development of trade.

On the other hand, landlocked countries remain isolated. They cannot develop trade due to absence of coastline. Such countries have poor economic development. For example, Afghanistan, Nepal.

The economic development in any region depends upon the quantity and quality of its people.

Where more suitable land is available, different economic activities are developed. For example, cities use land for various purposes such as industries, education, entertainment, transport, commerce, etc. Therefore, cities have economic development.

Hence, physical factors are said to affect the economic development of the region.

Question 2.
Measures to reduce regional imbalance.
Answer:

• The following measures along with numerous policies are considered by the government to reduce regional imbalance.
• The underdeveloped regions are identified and its economic, physical and social reasons for the non-development are studied.
• Regions which require monetary support in a particular sector or field are funded through sector-wise investments to improve the conditions.
• Subsidies are given to certain sectors. Investment is made for improvements of roads, schools, agriculture, irrigation, industries, housing, medical and health facilities, etc.
• Special attention is given to areas facing problems such as frequent droughts, deserts or hilly and tribal-dominated areas.
• The very important strategy to reduce regional imbalances is decentralisation of industries.

4. Give geographical reasons.

Question 1.
Regional development is dependent on physical setting.
Answer:

• The physical factors like relief, climate and location of the region affect the regional development.
• Regional development occurs where agriculture, agro-based industries and trade is developed in areas where there is plain relief and sufficient rainfall. For example, Asian countries have developed agriculture and trade of agricultural goods.
• Plain relief and sufficient rainfall encourage development of transportation and industries.
• There is poor development of economic activities in areas with unfavourable relief like mountains or hills and extreme climate. For example, in the northern part of Russia, economic development is poor due to extreme cold climate.
• Location of the country is an important factor. If there is a long and broken coastline, then there is development of trade and economy. For example, Japan has economically developed in spite of limited natural resources, due to the development of trade.
• On the other hand, landlocked countries remain isolated. They cannot develop trade due to absence of coastline. Such countries have poor economic development. For example, Afghanistan, Nepal.
• Thus, there is relationship between regional development and physical factors and therefore, we can say the regional development depends on physical factors.

Question 2.
Factors like literacy, poverty affect the regional development.
Answer:

• Literacy and poverty are the important factors affecting the regional development.
• High literacy rate determines the quality of human population. This increases the availability of employment opportunities and development of resources, which contributes to the economic growth and regional development.
• Due to high literacy rate, the population growth is controlled and resources are shared among less people in the country.
• However, poverty decreases the purchasing powers resulting in a decline in the demand for goods, which reduces the production and drops the economic development and GDP of a country.
• Hence, poverty and literacy affect regional development.

Question 3.
Development is not seen in the Himalayan region.
Answer:

• Relief and climate are the most important factors affecting the development of any region.
• The Himalayan region has high mountains with a steep slope. The climate is cold and the mountains are covered with snow. There is heavy soil erosion and hardly plain land, so agriculture is not developed.
• In this mountainous region, it is difficult and expensive to develop transportation facilities. Hence, there is poor development of industries.
• Since all above factors are neither suitable for agricultural, industrial or trade development is not seen in the Himalayan region.

5. Answer the following questions in detail.

Question 1.
What is a region?
Answer:

• A region is an area of a country or any part of the world having common features. Thus, there is a difference between two regions on the basis of its features.
• The common features may be physical (relief, climate, soil, natural vegetation, etc.), socio¬cultural factors (language, religion, etc.), man-made like political features (administrative or political boundaries).
• Regions may be small or large. The large regions include sub-regions. For example, the plateau region of India has various sub-regions such as Chota Nagpur plateau, Malwa plateau, Marwar plateau, Deccan plateau, etc.

The main characteristics of regions are :

• Regions have its geographical location mentioned in latitudes and longitude.
• Every region has a specific boundary, the area of another region starts beyond that boundary.
• The extent of a region depends upon the homogeneity of a region.
• There are sub-regions in one region and therefore regions can be arranged into different orders on the basis of same features.

There are two types of regions – formal and functional regions.
1. A formal region is also known as uniform region or homogeneous region. It is an area in which everyone shares in common one or more distinctive characteristics. It can be common physical characteristic such as relief or climate of the region. It can be socio-cultural or economic activity such as common language. For example, rice producing regions.

2. In some formal regions, there are boundaries. Thus, district, state or country may be formal region. For example, USA and Canada are the examples of formal regions.

3. In functional regions characteristics are not important but functions are more important.

4. In one functional region, there may be many political or physical regions but due to one common function it is said to be functional. For example, Mumbai metropolitan or Pune metropolitan regions.

5. Functional regions act as a focal point that connects surrounding areas by transportation and communication. For example, Mumbai metropolitan city is well connected with its surrounding areas through transportation.

Question 2.
On what factors are the regions differentiated? Give examples.
Answer:
A region is an area of a country or any part of the world with same common features. Thus, regions are differentiated on the basis of physical or man-made or socio-cultural factors.

For example, Chota Nagpur plateau region has plateau relief. Himalayan mountain region has mountainous relief. The desert region of Rajasthan has shortage of rainfall and very high temperature. Northern plain region has plain relief, fertile soil and moderate climate.

The region may be differentiated on the basis of man-made factors like political factors such as administrative boundaries or political boundaries. For example, Uttar Pradesh and Punjab are two different regions because they have different political boundaries and government bodies.

The region may be differentiated on the basis of socio-cultural factors such as language, religion or ethnicity. For example, in Mumbai there is an area, where people speaking Gujarati language live in one region. The Middle East countries form one region where people of Muslim religion stay together.

Thus, regions are differentiated on the basis of various factors.

Question 3.
Per capita income is not the real indicator of regional development. Explain.
Answer:

• The per capita income is the income of per person in the country or region. It is the ratio between the country’s national income and total population.
• Per capital income is an index of development because more the per capita income, higher the standard of living of people. But it is not always true.
• The per capita income gives an idea about the average income of people in the country but it does not explain how income is distributed among the people. Some people may be rich and some may be below the poverty line.
• The per capita income is related to only economic aspect of the country but it does not take into account literacy rate, health, sex ratio, age structure, life expectancy etc.
• Sometimes rise in per capita income is due to increase in prices of commodities.
• If the population is low the per capita income will be high, but the regional development will be slow, because such regions have shortage of skilled labour supply for further development. Therefore, we can say that the per capita income is not the real indication of regional development.

6. Find the correlation between land under permanent crops and GDP given in the table 7.5 using Spearman’s Rank Correlation. Write the conclusion in your own words.

Answer:

X₁ = Land under permanent crops
Y₁ = GDP
R₁ = Rank – 1, R₂ = Rank – 2, n = 12 (No. of pairs)
Rank correlation R = 1 – \(\frac {6Σ(R_1-R_2)^2}{n(n^2-1)}\)
= 1 – \(\frac {6×118}{12(144-1)}\)
= 1 – \(\frac {708}{1716}\)
= 1 – 0.412
= 0.588
= 0.59

The answer of correction between (1) Land under permanent crops (2) GDP is 0.59 or +0.59 which means there is a positive correlation between these two variables.

It is not perfect positive correlation (+1.0). It is slightly less than this i.e. (+0.59).

It means when the amount of land under permanent crops is more, GDP is also more and when the amount of land under permanent crops is less, GDP is also less.

This is because the production of crops contributes to the growth of GDP.

The answer 0.59 suggests that this is not true for all countries as there are other factors, activities, products which are responsible for the growth of GDP other than the production of crops.

(iv) The region G has the highest land use under category ‘other land’. Its GDP is 1391.5 billion dollars.
(v) The region I is having highest GDP in which there is 50% arable land, it means agriculture must be major activity.

The region A is having lowest GDP where land under permanent meadows and pastures is highest. It means there is limited development of agricultural activities.

It is surprising, region F where arable land is highest in percentage even then GDP is comparatively low, because the land under permanent crop is very less.

In region K, GDP is 5747.49 and land under forest is 66%. It must be because the development of lumbering activities and forest-based industries is greater.

The region G has the highest area under other land use (95.6%) and GDP 1391.25. This region must have developed activities other than agriculture and forestry.

Can you tell?

Question 1.
Read the table and answer the questions that follow. (Textbook Page No. 69)

(i) In which region do you think there are more resources available?
(ii) In which region do you think people are richer?
(iii) In which region do you think people may be happier? Why?
(iv) Do you think the given indicators or factors are enough to decide the standard of living of the people in the region?
(v) In which region would you like to stay? Why?
Answer:
(i) I think in region A more resources are available.
(ii) I think in region A people are richer.
(iii) People may be happier in region A because of higher per capita income, less population below poverty line, more urbanisation, more net sown area under irrigation.
(iv) I do not think the given indicator or factors are enough to decide the standard of living because other important factors like literacy rate, enrolment ratio / dropout ratio, sex ratio, crime rate etc., are not taken into consideration
(v) I will like to stay in region A because in this region per capita income is high, population below poverty line is low, percentage of urbanisation is highest, net sown and irrigated area is highest.

Question 2.
(i) Looking at the five stages of demographic transition theory, countries in which stage do you think, will be called developed?
(ii) Having looked at the various shapes of pyramids, which pyramid will represent a developed country? (Fig 2.1, Textbook Page No. 12)
(iii) After having answered both the questions above, what can you comment upon the role of population in regional development? (Textbook Page No. 70)
Answer:
(i) Countries in stage 4 and 5 will be called developed for e.g., USA, Sweden, Finland.
(ii) The pyramid (C) will represent a developed country.
(iii) The role of population in the regional development of any country is very important as man is a human resource. Quality of human resources is very important, which depends upon birth rate, death rate, expectancy of life, literacy ratio, male female ratio, mortality rate, etc.

A country having to qualitatively better population will help in the regional development of that country. For example, qualitatively population of the USA is better than population of India and hence, in USA there is better regional development than India.

Think about it

Question 1.
(i) Does development mean maximum utilisation of resources?
(ii) Does development consider environment as an indicator?
(iii) Can a region be called developed if it has sparse population or no population? (Textbook Page No. 69)
Answer:
(i) Development does not mean maximum utilisation of resources. Development of a region is the function of its resources and its population. There are many factors which affect the development of a region. For the holistic development of regions, skilled human resources and optimum utilisation of natural resources is necessary.

(ii) We must consider the environment as an indicator of development. Development at the cost of the environment is not real development. Since we ignore the environment while developing economy in the past 50 years, we are now suffering by many environment problems like global warming, etc.

(iii) Population is one of the most important factors in development. If there is sparse population or no population, then there will be shortage of man-power and resources will remain unutilized and therefore, quantity and quality of human resources is very important in the process of development.

Give it try

Question 1.
Draw a conclusion on the basis of the data given in table 7.4. Use Spearman’s Rank Correlation, find the correlation between the two variables. What can you comment about the development in this region? (Textbook Page No. 71)

Answer:

X₁ Percentage of malnourished children about to enter school.
Y₁ Government expenditure on education (% of total budget)
R₁ = Rank – 1, R₂ = Rank – 2, n = 8
Rank correlation R = 1 – \(\frac {6Σ(R_1-R_2)^2}{n(n^2-1)}\)
= 1 – \(\frac {6×104}{8(64-1)}\)
= 1 – \(\frac {624}{8(63)}\)
= 1 – \(\frac {624}{504}\)
= 1 – 1.24
= -0.24

The correlation between the percentage of malnourished children about to enter school and government expenditure on education is -0.24.
This value is very near to zero, which means no correlation. Hence, it is very slightly a negative correlation.

It means where the percentage of malnourished children about to enter school is more, the government expenditure on education is less e.g., in E region percentage of children is 31.7% but the expenditure is 4.09% and in C region percentage of children is only 3.4% but the expenditure is 7.10% (highest).

Considering the fact, we cannot consider this as well developed. There is no logical sequence in distribution of government expenditure on education. It is necessary that government authorities should take into consideration actual status of the region, need of the region before releasing grant to that region. This will surely help in proper allocation of the funds and overall development of the region.

Question 2.
Go through the fig. 7.2 and write two sentences on each factor. Tell how they will help in reducing regional imbalance. Also add some more to the list, if necessary. (Textbook Page No. 73)
Answer:
No country, in the world is having uniform regional development and thus, there is regional imbalance in development. Hence, a country must have a regional imbalance reduction strategy. Regional imbalance can be reverted through provision of public/services to backward areas by providing drinking water, education facilities and electricity to all.

It can also be reverted by making provision of infrastructure stimulus by allotment of special funds, development of special skills, good governance, support to infrastructural project and policy review and reform.

Question 1.
Look at the following data and answer the questions that follow: (Textbook Page No. 72)

(i) In which region is contribution of primary activities the least?
(ii) In which region is the contribution of primary activities the most?
(iii) In which region the contribution of tertiary activities is the most?
(iv) Which region has the highest HDI?
(v) Can you draw a conclusion on basis of the answers from Q (i) to Q (iv)?
Answer:
(i) In region A, the contribution of primary activities is the least.
(ii) In region E, the contribution of primary activities is the most.
(iii) In region B, the contribution of tertiary activities is the most.
(iv) In region A, there is highest HDI.
(v) We can conclude by saying that Human Development Index is high in countries where contribution of secondary and tertiary sector to GDP is high compared to the contribution of primary sector to GDP.

Region A, B, C and D have more than 30% contribution of secondary sector to GDP and more than 60% contribution of tertiary sector to GDP, it means these regions are developed regions.

The contribution of primary sector to GDP in region E is more but the contribution from secondary and tertiary sector is less compared to other regions, so region E is in the developing stage.

2. Give geographical reasons.

Question 1.
Human Geography is multidisciplinary in nature.
Answer:

• Human geography is the branch of geography dealing with human activities and their influence on culture, communities and economies.
• In human geography every social science studies separately has interface with branch of human geography; because of their spatial attributes.
• Social sciences like sociology, political science, economics, history and demography are very closely related with branches of human geography, such as social geography, political geography, economic geography and historical geography, respectively.
• Since, we study varied branches of geography in human geography, it is said to be multidisciplinary in nature.

Question 2.
Geography is dynamic in nature.
Answer:

• Most geographical phenomena whether physical or human are not static and can change overtime.
• In economic geography, we study economic activities as well as factors affecting their distribution and changes.
• In climatology we study changes in temperature and rainfall due to global warming. Depending upon the changes in climate, changes are made in cropping patterns.
• Geographers study relationship between production, distribution and geographical factors.
• For example, tea is grown on a large scale in the State of Assam due to high temperature, heavy rainfall, red soil, hilly relief, cheaper water transportation due to the Brahmaputra River and cheap and skilled labour supply from nearby States of Bihar and Orissa.
• We study weather over a period of about 30 years and decide climate of that place or population of a country or the world over a period of time. Since, changes occur time to time.
  Thus, geography is dynamic in nature.

Question 3.
Geography is dualistic in nature.
Answer:

• There are two contrasting approaches to study the subject of geography. They are possibilism and environmental determinism. This contrast in approaches is called as dualism in geography.
• Some geographers are of the view that nature is more dominant than man. It is called environmental determinism. According to them, when we study geography, we study the earth. We study how natural resources have influence on economic activities, as well as food habits of people.
• For example, in coastal areas fishing activity is more developed and fish is the main food of the people.
• Some geographers are of opinion that man dominates the nature. It is called possibilism. According to them man can make changes in nature due to his intelligence.
• For example, there are polyhouses even in polar areas, in which temperature is controlled artificially and vegetables are grown.
• There are many other thinkers who have different approaches in geography.
  Thus, the study of geography is dualistic in nature.

3. Write short notes on.

Question 1.
Physical Geography is related to various branches of science.
Answer:

• Almost every discipline, under natural and social sciences is linked with geography.
• Geomorphology, Climatology, Oceanography and Biogeography are the branches of physical geography.
• Geomorphology studies landforms, rock types, processes of formation of rocks, landforms, etc. Therefore, it is related to geology.
• Climatology studies elements of atmosphere such as temperature, winds, rainfall, humidity, natural disasters like cyclones, anticyclones, storms, etc. Therefore, it is related to meteorology.
• Oceanography studies oceans and seas on the surface of the earth, ocean currents, ocean routes, etc. Therefore, it is related to Hydrology.
• Biogeography studies the distribution of plants and animals, their species, ecosystems, etc. Therefore, it is related to biology.
• Knowledge of mathematics is important for cartographic techniques, such as drawing of maps and diagrams. Similarly, knowledge of statistics is useful to do data analysis since various statistical techniques and hypotheses testing are used in data analysis.
• Thus, physical geography is related to various branches of sciences.

Question 2.
Branches of Geography.
Answer:

• There are three major branches of Geography – Physical Geography, Human Geography and Geographic Techniques.
• Geography has various sub-branches; however, the four major sub-branches of Physical Geography are Geomorphology, Climatology, Biogeography and Oceanography.
• Human geography comprises of six sub-branches, Historical Geography, Political Geography, Economic Geography, Behavioural Geography, Social Geography and Population Geography.
• Geographic Techniques have four branches, namely, remote sensing, quantification methods in geography, cartography and Geographic Information System (GIS).

Question 3.
Latest trends in Geography.
Answer:

• Currently, the explanation of all geographic phenomena depends upon the cause and effect relationship.
• Geographers developed number of disciplines within its boundaries.
• Number of techniques for analysis and prediction through data collection and modelling are also developed by geographers.
• Due to the dynamic nature of geography, new things are added in the subject.
• Use of audio-visual media and information technology has enriched the database.
• The latest technology of software has brought about better opportunities in data collection, interpretation, analysis and presentation.
• Presently, the Use of GIS and GPS has become essential. Therefore, maps are made by using GIS software and have proved to be more accurate.
• Nowadays the use of mathematical modelling and computer models in applied geography has increased. They are used for prediction of weather changes or natural calamities.
• The above mentioned are all the latest trends in Geography.

Question 4.
Skills required for studying geography.
Answer:

• The skills required to study the methods and techniques used in geography have made the study of geography empirical and practical in nature.
• The study of geography is based on theory and observation. It is supported by the scientific study like data collection and data analysis through number of tools and techniques.
• The geographers developed skills for conducting surveys with the help of advanced technology. They have also acquired the skills to make use of satellite images for data collection.
• The geographers have attained the skills for experiments, data collection, data organisation, observation patterns, data analysis, research findings, etc.
• The geographers have learnt analytical techniques of data with the help of statistical techniques and representation of statistical data using graphs and maps.

4. Answer the following questions in detail.

Question 1.
Explain how the knowledge of Geography is important in our day-to-day life. Give examples.
Answer:

• The knowledge of geography is important in our day-to-day life because with geographical knowledge we can understand the basic physical systems that affect our everyday life.
  For example, the earth-sun relationship, water cycle, wind, ocean currents, etc.
• For the effective functioning of different places, we learn the physical and cultural characteristics of places.
• With the help of geography, we can understand the geography of the past, how geography had played an important role in the evolution of people, their ideas, places and environment.
• We can prepare a map of a province or territory, country and the world, so that one can understand the location of various countries. For example, the political map of the Asian continent gives idea about location of Asian countries.
• With the help of various distribution maps, we can understand distribution of minerals, crops, population, etc., in the world. For example, with the help of dot map we can understand spatial distribution of population in the world.
• With the help of economic geography, we can understand the development of economic activities in different countries of the \yorld and their correlation with physical and economic factors. For example, we can study the world’s leading areas in fishing activities and their reasons.
• With the help of climatology, we understand atmospheric phenomenon, such as cyclones, global warming, etc.
• The study of sustainable development in geography teaches us to appreciate the earth as humankind’s homeland and provide an insight for wise management decisions about the usage of the earth’s resources.
• With the help of geography, we can understand global inter-dependence to become a better global citizen.
• Thus, with the help of geography, we can study physical features, economic activities, trade, people, etc., in the world.

Question 2.
Discuss the relationship between Geography and other subjects.
Answer:

• Geography is related to almost every discipline under natural and social sciences. There are three major branches of Geography, namely, Physical Geography, Human Geography and Geographic Techniques.
• Geography has various sub-branches; however, the four major sub-branches of Physical Geography are Geomorphology, Climatology, Biogeography and Oceanography.
• In Geomorphology we study the formation and types of landforms, gradient, rock structure, etc. This is related to the subject of geology.
• In Climatology we study the atmospheric elements such as temperature winds, rainfall, humidity, natural disasters like cyclones, anticyclones, storms, etc. This it is related to the subject of meteorology.
• In Oceanography we study the ocean currents, ocean routes, coastal features, submarine relief, etc., of oceans and seas. This it is related to the subject of hydrology.
• In geography of soil, we study the components, layers, texture, and fertility of the soil, etc. This is related to the subject of pedology.
• Human geography comprises of six sub-branches, Historical Geography, Political Geography, Economic Geography, Behavioural Geography, Social Geography and Population Geography. In historical geography, we study the correlation of historical events with geographical factors. This is related to the subject of history.
• In Political Geography, we study the effect of geographical factors on political events. This is related to the subject of political science.
• In Economic Geography, we study the correlation of geographical factors and economic activities. This is related to the subject of economics.
• Similarly, Behavioural Geography, Social Geography and Population Geography are related to the subjects of psychology, sociology and demography respectively.
• Thus, it can be concluded by saying that geography has a strong relationship with other subjects in natural as well as human or social sciences.

Question 3.
Explain the nature of Geography in detail.
Answer:

• Geography is the study of the earth as a home of man, and various phenomena related to it.
• Therefore, geography is the study of the physical environment in relation to man. The physical environment has direct effect on cultural and social environments.
• The earth is dynamic in nature. Hence, we find variations in its physical and cultural/social environments.
• In geography we study the relation between the physical environment and production, distributions and their patterns and variations.
• Geographers study the location, geographical phenomena, whether physical or human, which are highly dynamic and its causes.
• Since geography is the study of space and time it makes geography dynamic in nature.
• In geographical study, the geographer tries to answer questions like what, why, where and when.

Skills required to study Geography.
Answer:

Class 12 Geography Chapter 8 Geography: Nature and Scope Intext Questions and Answers

Let’s recall

Question 1.
Dear students, you have been studying geography either as a part of Environmental Studies since Standard III or as Social Studies since Standard VI and as an independent subject since Standard XI. Your journey to understand our homeland earth began with the study of the cardinal directions in Standard III. In the consecutive academic years, you learnt various geographical concepts. Now just recall the various concepts that you have learnt till now and make a list of them. Also classify them under different categories given in the table 8.3. (Textbook Page No. 75)
Answer:

Can you tell?

Discuss the following points in class with reference to its importance in the subject matter of Geography. (Textbook Page No. 77)
Question 1.
Environment vs. Man
Answer:
Man and environment are inter-related. The environment influences the life of human beings who in-turn modifies the environment as a result of their growth, dispersal, activities, death, etc. Thus, all living beings including man and their environment are mutually reactive affecting each other in a number of ways and a dynamic equilibrium is possible between the two, i.e., human beings and environment are interdependent. If the natural environment helped in the development of different structures of the society on the one hand, the existence and quality of environment now rests on the responses of these social structures to the environment on the other hand.

The burning issues like quality of environment, disruption of earth’s natural ecosystems, environmental degradation and pollution, ecological imbalances, depletion of resources, etc., can be approached and solved only after considering the value judgments which may be determined by taking into account the consequences of ‘Environmental Improvement Programme’ on the entire society and society’s response towards the programme. However, all these depend on the interest and desire of the society in improving the quality of environment.

The interaction between the environment and man depends largely on the social and political system. The differential interactions are due to the uneven distribution of natural resources, uneven economic and social development, dissimilarities of demographic factors, varying view points of the governments and individuals towards the environment, etc.

Continuous and exceedingly increasing rate of exploitation of natural resources, industrialisation, technological growth, unplanned urbanisation and profit-oriented capitalism by the developed western world are responsible for grave environmental crisis and ecological imbalance not confined to their own countries but to the whole world.

The changes in the relationship between man and environment depend upon the change in organisation and attitude of man. To improve environmental stand and to maintain ecological balance, the following remedies are important

• Rapid growth of population
• Rational use of non-polluted water resources
• Use of organic fertilizers for agricultural growth
• To check soil erosion
• Restoration of forest resources
• To check pollution

3. Give geographical reasons.

Question 1.
Distribution of industries is uneven.
Answer:

• Distribution of industries depend upon various physical factors like climate, raw material, water and power supply, labour, transportation, land, etc., and economic factors like capital, market and government policies.
• Physical and economic factors vary from region to region and political factors vary from country to country.
• Industries are developed where physical and economic factors are favourable for their development.
• Thus, distribution of industries is uneven.
• For example, in India industries are concentrated in Mumbai, Chennai, Kolkata, Delhi, Chota Nagpur region and in the rest of India, agriculture is the only major economic activity.

Question 2.
Iron and steel industries are found in mineral rich area of Dhanbad.
Answer:

• Important raw materials used in iron and steel industry are iron-ore, limestone, dolomite, manganese and coal.
• All these raw materials are heavy, bulky and weight-loosing.
• The cost of transportation of these materials are very high.
• Dhanbad and its surrounding areas are the major iron-ore and coal producing areas.
• • Since this industry is using weight-losing raw materials which are available around Dhanbad, iron and steel industry is found at Dhanbad.

Question 3.
Fruit-processing industries are found in Ratnagiri and Sindhudurg districts of Konkan region.
Answer:

• Fruit processing industries use fruits as raw material.
• Ratnagiri and Sindhudurg districts are known for horticulture. They are major mango, jackfruit, cashew and kokum producing districts of Maharashtra.
• All these fruits are raw materials in fruit processing industry.
• These raw materials are bulky, weight-losing and perishable and hence the industry is located in Ratnagiri and Sindhudurg districts where fruits are grown in plenty.

Question 4.
What are the major factors which have hindered the growth of industries in South America?
Answer:

• Industries in the continent of South America are developed only in coastal areas of Brazil, Argentina, Chile and Peru.
• The hindrances in the growth of industries in South America are due to unfavourable physical factors such as dense forests in Brazil, deserts in interior parts of Argentina, Andes mountain range running along the west coast.
• The economic factors like limited capital, lack of modern technology and lack of transportation facilities etc., create hindrance in development of industries.
• Comparatively low density of population and lack of markets are the other factors responsible to have hindered the growth of industries in South America.

4. Write short notes on.

Question 1.
Footloose industries.
Answer:

• Footloose industry is a general term for an industry that can be placed and located at any location without effect of factors of location such as land, labour, climate and capital.
• The raw material used as well as finished products of these industries are very light so their location near the source of raw material or transport is not important.
• These industries often have spatially fixed cost, which means that costs of the product do not change despite where the product is assembled.
• Diamond cutting, computer chips and mobiles manufacturing are some of the examples of footloose industries.
• Advance technology like internet, email are used for raw material as well as marketing.
• These are generally non-polluted industries.

Question 2.
Public sector industries.
Answer:

• Public sector industries are owned by the state.
• The investments in public sector industries is done by the government. Also, marketing of goods is done through government agencies.
• Public sectors include public goods and governmental services such as military, law enforcement infrastructure (public roads, bridges, tunnels, water supply electrical grids, health, etc.).
• Bharat Heavy Electrical Limited (BHEL) is one of the largest engineering and manufacturing companies of its kind in India engaged in designing engineering construction.

Question 3.
Economics of scale.
Answer:
1. Economics of scale are the cost advantages that enterprises obtain because of various facilities
established due to basic industries in certain region.

2. Sometimes due to advantage of many favourable factors for industrial development in certain areas, there is concentration of industries in that area, which is called agglomeration of industries.

3. In these regions industries develop not due to any locational factors but due to economies of scale enjoyed because agglomeration of industries.

4. Due to the development of basic industries other ancillary industries which are complementary to each other also develop. For example, once cotton textile industry develops in any region, readymaide garment making industries, industries supplying dyes and chemicals, industries producing materials like thread, buttons, laces, etc., also develop.

5. Due to such agglomeration, the industries in that region get more profit compared to their investment due to economies of scale such as cheap transport, labour, financial facilities etc. For example, transport companies give concession, hence, the cost of transportation decreases.

6. Since industries in this region are complementary, it is easier to collect or supply goods from other industries of nearby areas. For example, dye making industries supply dyes to cotton textile industry and cotton textile industry supplies cloth to ready-made garment industries.

Question 4.
Role of transportation in industries.
Answer:

• Transportation facilities are important for the collection of raw materials and distribution of finished products.
• Low cost of transportation is the key factor in the location of industries.
• Transport network is crucial for sustained economic growth and development of a nation.
• Transport system helps to send raw material, fuel and machinery to different industries at the right time and runs the industry.
• Thus, transport plays a crucial role in the development of industries.

5. Differentiate between.

Question 1.
Weight-losing and Weight-gaining Industries.
Answer:

Weight-loosing	Weight-gaining
(i) Weight-losing industries are those industries in which raw material are relatively bulky but finished products are relatively light.	(i) Weight-gaining industries are those industries in which raw materials are relatively lighter than finished products.
(ii) Weight-losing industries are located near raw materials.	(ii) Weight-gaining industries are located near markets.
(iii) For example, sugar industries locate near sugarcane producing areas. 10 tons of sugarcane is required to produce 1 ton of sugar.	(iii) For example, cotton textile industries locate near the market because finished product cotton cloth is heavier than the raw material cotton.

Question 2.
Primary and Secondary Activities.
Answer:

Primary Activities	Secondary Activities
(i) Primary activities include activities, such as hunting, fishing, mining, agriculture.	(i) Secondary activities include manufacturing and constructions.
(ii) These activities are concerned with obtaining materials directly from nature. For example, fish from water or wood from trees.	(ii) These activities add value to the already existing products by changing their form, making them more suitable to satisfy our needs and wants.
(iii) Primary activities produce raw materials.	(iii) Secondary activities produce finished products.
(iv) Production of goods in primary activities depends upon natural factors.	(iv) Production of goods in secondary activities depends on technology, skill of labours and capital.

Question 3.
Basic Industries and Consumer Industries.
Answer:

Basic Industries	Consumer Industries
(i) The finished products of these industries are used by other industries.	(i) The finished products of these are used as raw material which are directly consumed by consumers.
(ii) For example, iron and steel industry provides steel as raw material to machine tool making or agricultural implements making industry.	(ii) For example, the medicines made in pharmaceutical industries are directly consumed by consumers.
(iii) These industries supply their products to others. Hence, they are called linkage products.	(iii) These industries supply their products to consumers. Hence, they are called as consumer goods industries.

6. Answer the following questions in detail.

Question 1.
Explain the physical factors affecting location of industries.
Answer:
Climate, raw material, water, power, labour, land and transport are important physical factors deciding the location of industry.

Extreme climate like too hot, too cold, dry and very humid climate are not suitable for industries. Generally, industries develop in areas of moderate climate.

Availability of raw material is essential for the development of industries. Industries using perishable, heavy, bulky and weight-losing raw materials are located in the areas of source of raw materials. For example, sugar mills near sugarcane growing areas.

Most of the industries require lot of water for processing, like cooling, washing etc. Such industries are located near lakes, rivers or other water bodies. For example, many industries are located around Great Lakes in USA.

Labour is another important factor deciding location of industries. Availability of skilled, semi-skilled and cheap labour is very important to work in industries. Hence, we generally find labour colonies are located where skilled and cheap labour is available.

Transport facilities are essential for transport of raw materials and finished products. Low cost transport is the key factor in the development of industries. Industries develop in the areas, where transportation network is well developed. For example , many industries are developed along Trans-Siberian railway line in Russia.

Industrial development need huge land for the construction of industrial units. Industries develop where cheap, plain and extensive land is available.

Industries need power supply, main sources of power supply are coal, oil, electricity and now a days wind energy, solar energy etc. Industries locate near coal mines, or availability of electricity. For example, industries concentrated around coal mining area of Ruhr region of Germany or industries concentrated near Khopoli hydro power station.

Question 2.
Explain the factors affecting location of sugar industries.
Answer:
The following are the factors affecting the location of sugar industries.

• Sugar industry is and agro-based industry.
• Sugarcane is the raw material in sugar industry.
• Sugarcane is perishable and weight-losing raw material.
• It is also heavy and bulky raw material.
• Taking into consideration all above characteristics of raw material used in sugar industry, it is always located in the areas of sugarcane production.
• In Maharashtra, Satara, Kolhapur, Ahmednagar, Sangli etc., are the sugarcane producing districts and the same districts have concentration of sugar industry.

Question 3.
Explain the economic and political factors affecting location of industries.
Answer:
The following are the economic factors affecting the location of industries.
1. Neatness to market : Transport cost is one of the important costs included in production cost of goods. If industries locate near the market there is saving on transport cost and goods reach to the consumers as early as possible. Some industries whose finished products are perishable or bulky or heavy, locate near the market. For example, ice cream making, furniture making or air craft making industries.

2. Availability of capital : Capital is required for land, construction, equipment, labour, transport etc. Therefore, industries are located in areas where banking and financial facilities are available. Generally, these facilities are available in big cities, therefore in India many industries are located in big cities like Mumbai, Chennai, Bengaluru, Ahmedabad, Kolkata etc.

The following are the political factors affecting the location of industries.
Government policies : The government policy of encouragement or discouragement directly affects location of industry.

• Sometimes government gives encouragement for development of industries in economically backward areas or to reduce the overcrowding in nearby cities by providing land, water, power at cheaper rate. For example, to reduce the overcrowding in Mumbai city, the government provided land, water, electricity at a cheaper rate in Navi Mumbai.
• The government policy regarding import, export, taxes, subsidies, etc., also affect location of industries. For example, liberal policy for industries in the State of Gujarat attracted many industrialists to set up industries.
• Development of SEZ : Due to the development of Special Economic Zone (SEZ) many industries are attracted in SEZ area. SEZ are developed to set up public sector or private sector industries, specially to increase export quality production in the country.

2. Give geographical reasons.

Question 1.
Not all rural settlements change into urban settlements.
Answer:

• The area between rural and urban is called rural-urban fringe.
• Villages are beyond the rural-urban fringe and cities have different land use pattern.
• In villages, land is mainly used for agriculture and related activities such as permanent pasture, grazing land, miscellaneous tree crops and groves, fallow land etc.
• In city areas land is mainly used for industries, residential purpose, recreation, transportation etc.
• Since the villages are far away from the city, they maintain their distinct identity and do not change into urban settlement.

Question 2.
In rural settlements, land use is related to agriculture.
Answer:

• Generally, the land in rural areas is used for agriculture and related activities.
• The classification of the land use in rural areas is done according to the Land Records Department.
• As per Land Records Department, the land in rural areas is mainly used for activities related to agriculture, such as some land is under permanent pastures and grazing lands or some under tree crops or culturable waste-land or fallow land etc.
• Thus, all the above types of land use around the rural settlements are related to mainly agriculture.

Question 3.

• The area between urban and rural areas is called rural-urban fringe.
• It has the characteristics of both urban as well as rural areas, since it is a transition zone between the two.
• Thus, in rural-urban fringe there is a mixture of urban-rural land use.
• In some rural areas apart from the land use for agriculture, some agricultural land has been converted into residential and industrial uses.
• The villages in rural fringe are partly affected by urbanization.
• Thus, rural-urban fringe has the characteristics of both urban and rural settlements.

Question 4.
Growth of urban areas is linked to land use.
Answer:

• Land use in urban areas is different from land use in rural areas.
• In rural areas the land use is closely related to agricultural activities like cultivation of different crops, plantation of trees, permanent pastures, grazing land, cultivation of tree crops, fallow land etc.
• On the other hand, land use in urban areas is varied and closely related to housing and economic activities.
• As the population of the urban area increases, more and more non-agricultural activities develop in urban areas.
• Growth of urban areas depends upon area under construction, industries, different types of institutions such as school, college, insurance companies, bank etc.
• Recreational activities, transportation are the other urban land uses.
• Thus, growth of urban areas is linked with land use.

3. Write short notes on.

Question 1.
Interrelationship between urban and rural settlement.
Answer:

• Settlements can be divided into urban and rural on the basis of their functions.
• Rural settlements are smaller than urban settlements.
• In rural areas agriculture and allied agricultural activities like livestock rearing, fishing, lumbering etc., are developed.
• In urban areas, industries, construction and economic activities like trade, transport and communication, banking and insurance are the important activities.
• The development industries need various raw material and services which are supplied by rural areas.
• For example, cotton grown in rural areas is supplied to cotton textile industries in urban areas. Everyday many rural people commute to urban areas to work in different activities.
• Thus, there is good interrelationship between urban and rural areas since they depend on each other.

Question 2.
Problems of urban settlements.
Answer:

• Most of the urban areas have very large size of population and density of population is also very high.
• When cities increase in size, many changes occur. These changes are related to land use and structure of the city.
• The large size of population and high density create number of socio-economic, cultural, infrastructural, administrative and environmental problems.
• The air, water and noise pollution, development of slums, traffic jam, overcrowding in trains and buses, waste disposal etc., are some of the serious problems in most of the urban settlements.

Question 3.
Suburbs
Answer:

• In the outer part of the urban areas there are small towns or small cities, they are known as suburbs.
• When big cities become overcrowded and overpopulated, the further development starts outside city area and thus suburbs develop.
• For example, Dombivali, Kalyan, Ambarnath etc., are the suburbs of Mumbai.
• Suburbs generally consists of residential housing and shops of low order, which act as central place for the local community.
• Often, suburbs are the most recent growth of an urban area and their end marks the urban fringe.
• With increase in population there is growth of suburb, the growth of suburbs may result in urban sprawl.

Question 4.
Mixed land use.
Answer:

• Mixed land use is observed in some of the urban areas.
• It is an area where different types of land use exist together.
• In some cities residential, industrial, commercial, administrative functions are found in an integrated manner.
• In many cities in developing countries one can find schools, clinics, houses, business shops at one place itself.
• Generally mixed land use is found in cities which are growing very fast, because land in the city is not sufficient to reserve certain areas for certain land use, therefore there is mixed land use.

4. Answer the following questions in detail.

Question 1.
Explain the characteristics of rural settlement.
Answer:

• On the basis of functions, settlements can be divided into two types – rural and urban.
• Agriculture and allied agricultural activities like fishing, livestock rearing, lumbering etc., are most economic activities in rural areas.
• The classification of land use in rural areas is done according to Land Records Department.
• As per Land Records Department the land in rural areas is mainly used for activities related to agriculture, such as some land is under agriculture, some under permanent pastures and grazing lands or some under tree crops or culturable waste-land or fallow land etc.
• Most of rural settlements are semi-clustered or fragmented and small in size.
• Primary activities like agriculture, lumbering, fishing, livestock rearing is more developed in rural settlements.
• In rural areas, sometimes agricultural areas are converted into residential or industrial areas.
• Many people in rural areas daily commute to city areas for work, thus rural and urban areas are connected with each other.
• There is an area between rural and urban area which is called rural-urban fringe, rural settlements are beyond the rural-urban fringe.

Question 2.
What factors are responsible for development of various patterns in settlement? Give examples.
Answer:
1. Patterns of settlements are affected by various physical factors like relief, soils, climate, availability of water supply etc.

2. Physical factors influence the type and spacing of settlements, which results into various patterns of settlements.

3. Type of soil and quality of soil are two important factors which affect rural settlements.

4. Fertile plains and valleys have thick, rich and fertile alluvial soil, which supports agriculture, so nucleated settlements develop in these areas. For example, most of the villages in Ganga plains have nucleated settlements.

5. Settlements develop as per the relief of that area. For example, Foothill settlements develop at the foot of mountain, hilltop settlements develop at the top of the hill. For example, hilltop settlement at Shimla or Manali.

6. In the areas of mountainous or hilly relief, due to inaccessibility, there are dispersed or isolated settlements. For example, dispersed or isolated settlements in Himalaya mountains.

7. Sometimes settlements develop along the coastline, canal, river, road, or railway line. They are in straight line; they are called linear settlements. For example, settlements along Konkan coastline and settlements along Mumbai-Pune road.

8. Climate also affects development of settlements. Areas of extreme climate are avoided by people. Therefore, such areas have dispersed settlements.

9. For example, due to extreme hot climate there are dispersed settlements in Rajasthan and due to extreme cold climate, there are isolated settlements in the polar regions.

10. Water is essential for human development. Therefore, many settlements develop around lakes or natural tanks, they are circular settlements.

11. Sometimes settlements develop at the confluence of two rivers, the settlements grow in all three sides, they are triangular settlements. For example, Karad town is on the confluence of Krishna and Koyna river.

12. Sometimes settlements grow around the mines, or any central object. This centre point provides source of livelihood to the people. Thus, radial pattern of settlement develops. For example, radial settlements around coal mines in the State of Bihar.

5. Differentiate between.

Question 1.
Land Use and Land Cover
Answer:

Land Use	Land Cover
(i) Land use describes the use of land by people for different activities, such as recreation, housing, agriculture, educational institutes etc.	(i) Land cover describes the physical surface covering the land such as forest rock, ice, sand, water etc.
(ii) For example, in any city, people may use some land for housing, some for recreation, some for sports ground etc.	(ii) For example, in any area land may be covered by natural factors such as vegetation, river, sand dune, snow covered mountain etc.
(iii) Land use may change from place to place depending upon type of land and need for the people.	(iii) Land cover is natural factor it hardly changes unless man purposefully makes changes in it.
(iv) Land use cannot be studied by the satellite imagery alone.	(iv) Land cover can be studied by satellite imagery.

Question 2.

Answer:

Barren Land	Non-agricultural Land
(i) The land which is not used for any human activity is called barren land. In other words, it is wasteland.	(i) The land which is used by man for various human activities except agricultural activity, is called as non-agricultural land.
(ii) For example, hilly or mountainous land, desert land, ravines, swampy and marshy land etc.	(ii) For example, land used for housing, industries, construction of roads, railways etc.
(iii) Generally barren land cannot be used for agriculture or other activities with available technology.	(iii) Due to the development of secondary or tertiary activities there is increase in the used of non-agricultural land.

Question 3.
Radial pattern and Circular Pattern
Answer:

Radial Pattern	Circular Pattern
(i) In radial pattern settlements grow around certain object.	(i) In circular pattern settlements grow around water body.
(ii) They develop near temple or a centre of commercial activity.	(ii) They develop near lake or natural tank.
(iii) For example, settlements near Vindhyachal in Uttar Pradesh.	(iii) For example, settlements around Nainital lake in Uttarakhand.

Question 4.
Nucleated and Dispersed Settlement
Answer:

Nucleated Settlement	Dispersed Settlement
(i) Settlement where buildings or houses are grouped or clustered around a central point or nucleus is known as nucleated settlements.	(i) Settlement where buildings or houses are scattered or dispersed, is known as dispersed settlement.
(ii) Houses or buildings are very close to each other. There may be common wall between two houses.	(ii) Houses or buildings are far from each other. One house may be at a distance of half a kilometre from the other.
(iii) Geographical factors are favourable such as spring or fertile river valley.	(iii) Geographical factors are not favourable such as extreme climate, barren land etc.
(iv) For example, settlements in river valleys.	(vi) For example, settlements in the desert of Rajasthan.

7. Write a note in your own words about how land used in Lonar city has evolved. Refer the map on textbook page no. 30.

Answer:

• Two maps of Lonar city are given. One map is of the year 2005-06 and another is of 2015-16.
• These two maps show the changes in land use that have taken place in the span of 10 years.
• The following changes have been registered.
• There is no change in the size of Lonar lake.
• The area occupied by Lonar city has increased substantially.
• Forest area around the lake has increased.
• An area under waste land/ scrubs have increased.
• Around the temple in the southeast, on the waste scrub land a new rural hospital, government hostel, government ITI, Tahsil office etc., has been developed. This newly developed area has been named as Krishna Nagar, which is not in 2005-06 map.
• To the north-east of the Lonar city two more building have been constructed. One is central public school and another is civil and criminal court.
• To the south of the temple in the heart of Lonar city built up residential area is spreading over built up residential sparse.
• Overall built up residential sparse is increasing in all directions around Lonar lake and south-eat of the Lonar city and thus there is encroachment over agricultural land.

8. Read the given passage and answer the following questions.

Different types of human settlements include hamlets, villages, small towns, large towns, isolated places, cities and conurbations. In some systems, types of human settlements are broken up into urban, suburban and rural; for example, the U.S. Census Bureau divides settlements into urban or rural categories based on precise definitions. Small settlements, such as hamlets and villages, have low populations and restricted access to services, larger types of settlements, such as cities, have higher populations, higher densities and greater access to services.

For example, a village may have only one or two general stores, while a large metropolis may have many specialized stores and chain stores. These differences are known as low-order service settlements and high-order service settlements. Larger settlements also have a sphere of influence affecting surrounding settlements. Settlements may also be divided by the site chosen, such as sites selected based on resources, trading points, defensive sites, shelter and relationship to water resources. The functions of human settlements also differ, as settlements may be established as ports, market towns and resorts. Types of rural settlements may also be classified by function, such as proximity to farming, fishing and mining. Settlements that focus on one economic activity are called single functional settlements. Human settlements may be permanent or temporary. For example, a refugee camp is a temporary settlement, while a city is a permanent settlement.

Question 1.
Which human settlements are mentioned in the passage above?
Answer:
Hamlets, villages, small towns, large towns, isolated places, cities and conurbations are the types of settlements mentioned in the passage.

Question 2.
On what basis are urban and rural areas classified?
Answer:
Settlement are classified on the basis of the size of population, density, access to higher order and lower order services, site chosen, functions, permanent or temporary etc.

Question 3.
What are the functions carried out in rural settlement?
Answer:
Functions carried out in rural settlements are farming, fishing, mining, one or two general stores, etc.

Question 4.
Explain the difference between low-order services and higher order service settlements.
Answer:

• The hamlets and villages have low population and restricted access to lower order services.
  For example, a village may have only one or two general stores. They are called low order settlements.
• Large metropolitan cities have higher population, higher density and greater services of higher order.
• For example, large metropolitans may have chain stores, malls, departmental stores, super markets etc. They are called higher order settlements.

Can you tell? (Textbook Page No. 27)

You know what is urban and what is rural. What will you call the area that lies between them?
Answer:

• The area between urban and rural areas is called rural-urban fringe.
• It is characterised by the urban as well as rural characteristics, since it is transition zone between the two.
• Thus, in rural-urban fringe there is a mixture of urban-rural land use.
• In some rural areas apart from the land use for agriculture, some agricultural land has been converted into residential and industrial uses.
• Thus, villages in rural fringe are partly affected by urbanization.
• Thus rural-urban and fringe have the characteristics of both urban and rural settlements.

Let’s recall (Textbook Page No. 24)

Can you differentiate between urban and rural settlements?
Answer:

• On the basis of functions, settlements are divided into two types – rural settlement and urban settlement.
• There is difference in land use in rural and urban settlements.
• In rural areas the land use is closely related to agricultural activities like cultivation of different crops, plantation of trees, permanent pastures, grazing land, cultivation of tree crops, fallow land etc.
• Where as in urban areas land use is for industries, construction and economic activities like trade, transport and communication, banking and insurance etc.
• Urban settlements are large and compact, since population is more compared to available land.
• Rural settlements are small and dispersed, since population is less compared to available land.

Think about it (Textbook Page No. 24)

Can a town have only one function? Why do the cities become multi-functional?
Answer:
1. Towns do not have only one function.

2. Some towns have one important and major function. They are known by that function. But they have many other functions also. For example, Shirdi in Maharashtra is known for religious function but it has other functions like tourism, education, commercial etc.

3. Cities become multifunctional as they grow. With increase in population demand for various functions increases. As cities grow in size many changes occur and therefore land use also changes.

4. For example, when any city develops as industrial centre, its main function is industries. But as people start coming to that city for employment opportunities, the city grows. Then other functions like educational institutes, business centres, recreational centres, etc., functions develop to fulfil the needs of increasing population. Thus, cities become multi-functional.

Question 1.
Observe Fig. (Textbook Page No. 21) and answer the following questions.

(i) Where are humans’ settlements likely to develop: A, B, C, D or E? Why?
(ii) In the above figure in which place human settlement is not likely to develop? Why?
(iii) Looking at the figure above, what factor do you think could contribute to the development of human settlements?
(iv) Can economic factors be important along with physical factors for the development of human settlements?
(v) Do physical factors affect the economic activity of human settlements?
(vi) Make a list of factors which affect development of settlements in an area.
Answer:
(i) Human settlement is likely to develop at C and D.
The most important factor responsible for the development of settlement is river. Hence, agriculture seems to be the most important activity and development of agriculture needs fertile soil and water supply which is readily available here.

(ii) Human settlement is not likely to develop at A and B. This is because of steep slope and rugged terrain.

(iii) The most important factors that could contribute to the development of human settlements are availability of water from the river and fertile soil on the bank of river.

(iv) Yes, economic factors are equally important along with physical factors for the development of human settlements. For example, industries need development of roads to carry raw material or agriculture also needs development of roads. Many settlements are developed along roads or railway lines.

(v) Yes, physical factors affect the economic activity in the development of human settlement. For example, agriculture is’ an important activity which is affected by relief and water supply. It can be developed where fertile soil and sufficient water supply is available.

(vi) The factors which affect development of settlements are relief, terrain, climate, soil, water supply, altitude, drainage, minerals etc.

(b) Perth – Vladivostok
(c) Sydney – Vancouver
(d) Vancouver – Vladivostok
Answer:
(b) Perth – Vladivostok

3. Give geographical reasons.

Question 1.
Tertiary activities include both services and exchapge.
Answer:

• Transportation, communication, trade and commerce are the main tertiary activities.
• Road, rail and airways are the important modes of transportation, which help in exchange of goods and services. Therefore, it is a service activity.
• Transportation provides facilities for the movement of goods from areas of surplus to areas of scarcity produced in primary and secondary activities.
• Credit facilities, banking facilities, marketing are also tertiary activities, they provide services to people.
• Postal services, shopkeepers, vegetable sellers, fruit sellers, etc., are also included in service activities.

Question 2.
The proportion of airways as means of transportation is increasing.
Answer:

• Air transport is an important enabler to achieve economic growth and development.
• In the global world, there is exchange of goods between countries. Therefore, there is more use of air transport to carry perishable, valuable and light goods from surplus areas to scarcity areas.
• It facilitates integration into global economy and provides vital connectivity on a national, regional and international scale.
• Nowadays tourism is the fastest growing industry; air transport is more used for international tourism.
• Therefore, the proportion of airways as means of transportation is increasing.

Question 3.
Geographical diversity is responsible for trade to occur.
Answer:

• The geographical diversity is the set of physical, human and cultural elements differentiated from each other that converge in the relatively small geographic space that is part of the same zone, region or country.
• If you take into consideration natural regions of the world, each region is different from another.
• The natural resource available in one country will be different from the ones available in different regions.
• There is variation in climate, soil, minerals, forest, relief, water supply etc.
• Depending upon the availability of geographical factors, there is specialisation of certain economic activities in certain areas and there is trade from surplus areas to scarcity areas. For example, in one region, plenty of oil is available while in another region no oil reserves are available.
• This variation in distribution of oil will be responsible for the development of trade between oil rich and oil poor countries.
• Thus, geographical diversity is responsible for trade to occur.

4. Write short notes on.

Question 1.
Importance of satellite as means of communication.
Answer:

• A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via. transponder.
• Communications satellites are used for television, telephone, radio, internet and military applications.
• The information about physical and human factors is obtained from satellite communication.
• Satellite communication is used in remote islands, in some countries and continents where landline telecommunication is rare or not available.
• As television becomes the main market, its demand for satellite communication becomes very important.
• Satellites are also used for internet communication, military communications, etc.
• Thus, importance of satellite as means of communication is increasing.

Question 2.
Role of transportation in trade.
Answer:

• Transport support trade and industry in carrying raw material to the place of production and distribution of finished products for consumption.
• Transport means to make goods available to consumers.
• Transport makes possible movement of goods from one place to another with great ease and speed.
• Trade means exchange of goods and services. In trade there is movement of goods from surplus areas to scarcity areas. The movement of goods is possible only because of transport.
• In other words, without the help of transport development of trade is not possible.
• Thus, transport plays an important role in economic development and globalisation of trade.

Question 3.
Tourism and GDP.
Answer:

• Tourism is vital for the success of many economies around the world.
• Tourism boosts the revenue of the economy, creates thousands of jobs and develops the infrastructures of the country.
• It also creates jobs in agriculture, communication, health and educational sectors.
• The government that depends on tourism, invests a lot in the infrastructure of the country. They construct new roads and highways, develop parks, improve public places, and set up airports, etc.
• With augmenting facilities, more and more tourists are attracted in such countries, thus, there is boosting of the GDP.

6. Answer in Detail

Question 1.
Explain the factors affecting trade between two countries.
Answer:
Trade refers to transfer of goods or services from one person to another or from one country to another. Factors which affect the trade are natural resources, climate, population, culture, economic cost, specialization, etc.

Natural resources : Distribution of natural resources is uneven. The natural resources available in one country differs from another. Because of this uneven distribution of resource, there is trade between resources surplus and resource deficit.

Climate : Climate mainly affects the plants and animals in a region. In the areas of different climate, there are different types of plants and animals. Example, in the tropical countries like Sri Lanka whose major export is tea or Malaysia and Indonesia, whose major export is rubber. This occurs naturally because of favourable climate for growing tea and rubber plants in these countries.

Population : Population size, distribution and density are different in different countries. This leads to difference in production and consumption and hence trade occurs.

Standard of living can also determine the demand for various goods and services. The country with less population depends more on trade because fewer human resources is engaged in production of goods.

Culture : Some countries are known for their specific art and craft, based on their culture, specific production of goods which have worldwide market, for e.g., Kashmiri shawls or Iranian carpets.

Economic Cost : Cost of production is the major factor in the process of production. It is cheaper to import certain goods than producing it in the country itself. For example, it is cheaper to import tea from India and Sri Lanka than producing it in England.

Specialisation : Due extremely favourable factors of production, some countries have specialisation for certain goods and they have name and fame in the world market, so they develop export trade. For example, watches of Switzerland or electronic goods of Japan or tender beef of Argentina.

Government Policy: Government policy about export or import affects trade. For example, Government may increase import duties of some goods, to encourage people to buy domestic goods. Thus, import trade of those goods goes down.

Class 12 Geography Chapter 6 Tertiary Economic Activities Intext Questions and Answers

Think about it.

Read the following comprehension and answer the questions that follow:

There are three friends from different back-grounds. They decided to become entrepreneurs after graduating from the same college. Rohit is a farmer’s son. He pursued his bachelor degree in the Arts faculty. He was thinking of continuing his father’s profession but at a different level. He wanted to grow export-quality agricultural products in his two acres of farmland.

Sejal is the daughter of a businessman. They produce and sell bakery products on a wholesale basis. She has passed her degree in Science. She wants to become an entrepreneur in Fast Moving Consumer Goods (FMCG) products. Asif is a son of a small hotel owner. He has passed his graduation in Event Management. He wants to start his own company of Event Management.

After graduating with good grades, they decided to help each other and begin their careers. Rohit, Sejal and Asif tried to find out information about haw to start their businesses. They tried to get maximum information regarding their businesses. They wanted to plan, organise and then establish their start¬ups. During this period, they found information regarding their businesses.

Rohit found out that he will have to do major changes in his farmland to grow export-quality products like lily, orchid flowers and fruits like kiwis, dragon fruits, etc. He will have to maintain moisture and temperature in the air. He will also need to use special fertilizers to maintain the soil’s pH value.

He also came to know that he has to take help of the Agricultural officer from the same Taluka. More importantly, he has to take out a licence to establish a business. He also got to know that he will need an account which can be used for foreign transactions. He also got information from where, he would get saplings for the export-quality products. He came to know that, these flowers are in great demand in Gulf countries and they give high returns too. As these countries are within the reach of an hour or two by air, the flowers can remain fresh and retain their quality. He also decided to visit few vendors from these countries to directly setup his business.

Sejal realised that toothpaste is a product which is required daily by the people. Since her background was from Science, she decided to derive an advanced formula which will be good for dental health. She also took help from a cousin brother from the Pharmaceutical industry.

She came to know that she needed the following things to set up the industrial unit:

• Machinery and labour force to work in the plant.
• Land for setting up the plant.
• NOC from competent authorities before taking the product to the market.
• Other licenses like NOC from fire service department.
• Industries that will give tubes to fill ready toothpaste and cartons to wrap the product.
• Appoint an advertising agency to promote the product.

She was reluctant for this start-up since it required land and a large capital investment. But she felt relieved that due to the Government’s Start-up schemes, she can get subsidised loan. Her father helped her solve her land problem. He had a small piece of land near her town which was sufficient for this purpose. He arranged for other basic amenities like water, electricity, etc. which are required for an industry. He leased out that plot to Sejal.

Asif realised that he mainly needed services and labour for his start-up, which he can arrange by hiring them from various agencies like caterers, florists, hall owners, band players, sound systems, etc. He also understood how to take permission from various competent authorities to arrange various events. He realised that it will be good if he opens up an office to start his business in the market. To advertise his start up, he got a brochure designed and printed visiting cards for marketing his services.

After planning for a year, all the friends started their entrepreneurship in their respective businesses. As their businesses have been established as per their likings; they are enjoying their work. Their businesses are now their passions.

Question 1.
Consider the following conditions a, b, and c and answer the questions that follow
(a) There are two countries ‘A’ and ‘B’. ‘A’ produces 500 tonnes of wheat by employing 200 labourers. ‘B’ produces 1,000 tonnes of wheat by employing 300 labourers.
(b) Country ‘C’ produces 300 kg of tea and ‘D’ produces 500 kg of coffee. ‘C’ does not produce coffee and ‘D’ does not produce tea.
(c) Country ‘E’ has expertise in water engineering and agriculture. Country ‘F’ has expertise in metro-making. (Textbook Page No. 59)
(i) Will the trade take place between A and B in condition (a)?
Answer:
No, trade of wheat will not take place in between A and B because both are producing wheat.

Question 2.
Will trade take place between C and D in condition (b)?
Answer:
Yes, trade will take place between C and D in condition (b) because C country produces tea and D country produces coffee. Since they produce different products – tea and coffee, they will exchange their products through trade.

Question 3.
If trade occurs between A and B in condition (a), what does it tell you about the conditions of countries in term of their economy?
Answer:
Firstly, both countries are producing wheat and therefore, if their production of wheat is sufficient for their population, trade will not take place.
Secondly, per capita production of wheat in country A is less than country B. As a result, the cost of production of wheat in country A is more than B country.

Under the above conditions if country B is ready to export wheat to country A, country A will get wheat from B at the lower cost than the production cost in their country and trade in wheat will take place and both countries will be economically benefited and can improve their economy.

Question 4.
If trade occurs between C and D in (b), what does it tell you about the climate of the countries?
Answer:
Country C produces tea and country D produces coffee. So country C can export tea to country D and country D can export coffee to country C and trade will take place between C and D depending upon market for tea and coffee in respective countries.

As far as climate is concerned in both countries there must be tropical climate because cultivation of tea as well as coffee needs same type of climate conditions. Since both crops requires same climate, both can produce tea and coffee too and avoid trade or one can specialize in tea cultivation and another in coffee cultivation and develop trade.

Question 5.
Considering that trade occurs between two countries in condition (c), what does it tell you about the human resources of the countries?
Answer:
Country E has developed technology in water engineering and agriculture. While F has developed technology in construction of the metro. This shows that both countries are technologically advanced and hence their human resources are very rich.

Question 6.
Make a list of factors which affect the trade between any two countries.

3. Write short notes on.

Question 1.
Plantation agriculture
Answer:

• Plantation agriculture is an extensive type of agriculture having large farm size on which one crop is cultivated. This is known as monoculture.
• Care has been taken to maintain the quality of the crop using scientific methods. This type of agriculture is modern as well as capital intensive agriculture.
• Since most of the work is done by human labour this type of agriculture is also referred to as labour intensive agriculture.
• The plantation crops once grown provides production for 10 to 15 years.
• Tea, coffee, rubber, cocoa, cashew nut, spices, etc., are the most important crops. For example, Rubber plantations in Kerala or tea plantations in Assam.
• Malaysia, Indonesia, Sri Lanka, India, Thailand, Vietnam, Caribbean islands are the important countries where plantation agriculture is practiced.

Question 2.
Physical factors and fishing
Answer:
Development of fishing requires specific physical factors.
Therefore, it is developed on a commercial scale where physical factors are favourable for fishing.

The following are the important physical factors, which can be responsible for the development of fishing.

• Broad continental shelf, with shallow water is favourable. For example, continental shelf along the eastern coastline of Japan is broad and water is shallow.
• Warm and cold ocean currents should meet near the coastline, so that plankton (favourite fish food) is available in plenty.
• Broken coast line which provides natural ports and harbours.
• Cold climate is favourable for natural preservation of fish.
• Since above all physical factors are present on the north-east coast of USA, north western coastline of Europe as well as in Japan, commercial fishing is well developed.

Question 3.
Lumbering on a commercial scale
Answer:
Commercial lumbering is well developed in coniferous forest region of Canada, North Western Europe and Soviet Union.

The important factors responsible for the development of commercial lumbering in the above areas are as follows.

• In coniferous forest one species of trees are found over an extensive area.
• Coniferous trees are tall and away from each other so lumbering is easy.
• Wood is soft and durable. Coniferous forests provide good raw material for paper and pulp industry and furniture making industry.
• Due to good quality of wood (softwood) it has great demand in the world market.
• Cool and pleasant climate is favourable for labour to work throughout the year.

Question 4.
Hunting and loss of ecosystem
Answer:

• Before the development of agriculture hunting was the important activity of man to obtain food.
• Many animal species were becoming extinct because of large scale hunting.
• Therefore, to protect the ecosystem, in many countries commercial hunting is banned.
• Presently, many laws are being passed to conserve and protect the animals and ecosystem.
• Yet, many tribal people such as Eskimos in Tundra region, Pygmies of Equatorial Selvas, Bushmen of Kalahari, Sentinels in Andaman etc., are still doing hunting.

4. Give geographical reasons.

Question 1.
Agriculture is done on a large scale in India.
Answer:

• More than 46 percent of the total population of India is engaged in Agricultural Activities.
• In northern India, we have extensive fertile alluvial soil in Gangetic plains most suitable for the development of agriculture.
• In south peninsular India, there is very fertile black cotton soil suitable for a variety of crops.
• Along the coastal lines fertile soil is found in the deltas of river Krishna, Godavari, Mahanadi, Tapi, Narmada, etc.
• Many rivers like Ganga, Yamuna, Godavari, Tapi, Narmada and their thousands of tributaries and canals provide water for irrigation.
• The economic and social factors, including labour, market, capital, transportation facilities, storage facilities and government policies, etc., are all favourable for the development of agriculture.

Question 2.
Mining is developed in Chhota Nagpur plateau of India.
Answer:

• The distribution of minerals is highly uneven in India.
• The geology of Chhota Nagpur region is very rich in minerals.
• There is concentration of minerals like iron-ore, manganese, mica, copper, limestone, and lead in Chhota Nagpur region.
• The government policy, capital investment in mining activities, technological development, availability of skilled labour, transport facilities, etc., are favourable for the development of mining activity in Chhota Nagpur region.
• Development of many industries related to minerals are located in this area, which gave boost to the development of mining activities.

Question 3.
Lumbering is developed on a large scale in Canada.
Answer:

• Lumbering is one of the most important economic activity in the areas covered by coniferous forest in Canada.
• In Canada coniferous forest grow in large belt, since the climate is suitable for the growth of coniferous trees.
• In these forests only one species of trees grows in one area which is favourable for the lumbering.
• The development of lumbering depends upon the type of wood, climate, market and transport facilities.
• Commercial lumbering is developed in Canada because there is coniferous forest region, which provides soft wood, which is easy to cut, carry and durable.

Cool climate of Canada, well developed transport facilities for the movement of logs, use of machinery for logging, large demand in local and international market for paper and pulp industries, limited development of other economic activities due to extreme cold climate are the other factors responsible for lumbering in Canada.

Question 4.
Extensive agriculture is a commercial type of agriculture.
Answer:

• Extensive commercial agriculture was developed in temperate grassland region in Steppes, Prairies, Downs, Pampas and Veld grasslands.
• In these grassland areas population density is low and size of farms is very large from few hundred to thousand acres.
• There is extensive use of machinery from sowing to harvesting.
• Modern and scientific methods of agriculture are used, so production is large.
• The per hectare production is low whereas per capita production is high.
• Since population in those grasslands is very low and there is surplus production,
• Therefore, large quantities of food grains are available for export, so this agriculture is known as commercial type of agriculture.

Question 5.
Lumbering is practiced more in coniferous region than in tropical region.
Answer:

• Lumbering activity depends upon nature of wood – hard or soft, density of forest, number of species in the forest, transportation facilities, use of machinery and market.
• In coniferous forest region trees provide softwood, which is easy to cut and durable.
• In coniferous forest region one type of species are found in extensive area, so lumbering is easy.
• In coniferous forest region there is use of machinery for lumbering and transport facilities are also well developed.
• There is lot of demand for softwood in local and international market, hence commercial lumbering is more developed.
• On the other hand, in tropical region, density of trees is very high, different types trees grow in close proximity, so lumbering is difficult.
• In tropical region surface movement is difficult and transport facilities are not developed because of marshy land.
• In tropical region there is no local market since trees provide hardwood and therefore commercial lumbering is not developed.

Question 6.
Hunting has been banned.
Answer:

• In the older days hunting was the most important primitive activity of man to obtain food.
• Since agriculture was not developed, it was the only source of food for man.
• As a result, large number of animals were killed to such an extent, that some of the species
  of animal have become extinct or at the verge of extinction.
• In order to conserve and protect animals, hunting is banned all over the world.

6. Answer the following questions in detail.

Question 1.
What are the factors affecting commercial fishing?
Answer:
Following factors affect commercial fishing.

• Extensive continental shelf with shallow water. For example, Dogger bank fishing area.
• Confluence of warm and cold ocean water currents, which is favourable for the growth of plankton. For example, Gulf warm pcean current and Labrador cold current meet together near Dogger bank on North Eastern coast of North America.
• Broken coastline for the development of ports and -.
• Traditional skills of some local people who are expert in fishing.
• Large size of population to provide demand for fish.
• Limited land to grow protein rich food, so that fish becomes staple food of people.
• Use of advanced fishing boats and fishing nets.
• Cool climate for natural preservation of fish.
• Forest resources to provide wood for ship building industry.

Question 2.
Write a note on Intensive Subsistence agriculture.
Answer:

• Intensive subsistence farming is practiced in densely populated countries like China, India. Japan, Sri Lanka and east Asian countries.
• Since there is large population and limited fertile agricultural land, there is small land holding.
• Farmers work intensively to get maximum yield from available small land.
• Rice is the dominant food crop produced in this region.
• Mostly manual labour and animals are used for all agricultural activities.
• Most of the production is consumed locally and hence no surplus is available for export.
• Yield per hectare is high but yield per capita is low.

Question 3.
Give characteristics of Market Gardening.
Answer:
The following are the characteristics of market gardening.

• It is a modern type of agriculture developed mainly on the fringe of highly industrialised and densely populated urban areas.
• Vegetables, fruits, milk, eggs, meat etc., are the important products produced.
• Size of the farm is very small like garden.
• Scientific and technological knowledge as well as manual labour to some extent is used in production.
• Use of capital is very high.
• Natural organic manures and chemical fertilizers are used.
• Developed in areas lying at the distance of overnight journey by trucks, so that perishable products can be carried to nearby city market as early as possible. For example, vegetables and fruits grown at Vasai and Virar are carried to Mumbai.

Question 4.
Write a note on the areas in the world practicing commercial animal husbandry.
Answer:

• Commercial animal husbandry is practiced in 30°N to 60°N latitude, and 30°S to 55°S latitudes.
• Commercial animal husbandry is practiced in temperate grassland regions of steppes in Russia, prairies in North America, downs in Australia and velds in South Africa and Pampas plains of Argentina.
• In these areas there is cultivation of crops as well as grass for animals.
• In these areas agriculture and animal husbandry is done together.
• This type of farming needs huge capital investment and more use of modern machinery, advanced technology, market and large land.
• In North and South America, it is carried with the help of advanced technology on a commercial scale.

Question 5.
Mining is dependent on the extraction of naturally occurring minerals. Explain.
Answer:

• Mining is one of the oldest economic activity of man.
• Man cannot produce minerals that are naturally found in the crust of the earth.
• This activity solely depends on the presence of minerals.
• It also depends on geology of the region, value of minerals, quality of minerals, capital investments, technology and availability of skilled labour, etc.

Question 6.
Write in detail about the characteristics of primary economic activities.
Answer:

• Hunting, gathering, fishing, rearing animals, mining and agriculture, etc., are the important primary economic activities of man.
• These activities are solely dependent on nature.
• Primary activities mean extraction of natural resources.
• These activities mainly produce raw materials required in different types of industries.
• Natural calamities affect most of the primary activities.
• In developing countries very large proportion of working population is engaged in primary activities, since there is less use of machinery.
• In developed countries there is less proportion of working population engaged in primary activities, since there is more use of machinery.

(i) Which economic activities are shown in the following map?
(ii) In which region do you don’t find any activity? what could be the reason?
(iii) In which latitudes do you primarily find the distribution of lumbering activity?
(iv) Why is fishing occupation only found in certain areas in the oceans?
(v) Which primary economic activities are mostly found in Europe?
(vi) What production does the symbol of mining shown in seas and oceans depict?
(vii) In which continent mining is not found?
(viii) In which ocean is the world’s fishing mostly carried out?
(ix) Which primary economic activities are found to the south of Tropic of Capricorn?
(x) Which primary activity is found in the islands of South East Asia?
(xi) Considering all four continents, in which continent do you find less agriculture being practiced?
(xii) Write a paragraph on relationship between latitudinal extent of agriculture and climate in your own words.
Answer:
(i) Agriculture, animal husbandry, fishing, mining and lumbering are the economic activities shown in the map.
(ii) In Antarctica region we do not find any activity because of permafrost and uninhabited continent.
(iii) Lumbering activity is primarily found in 50° to 70° North latitudinal region.

(iv) Fishing can develop only in those areas in the oceans where continental shelf is broad and shallow, meeting of cold and warm ocean water currents and availability plankton food for fish, cool climate etc. Since these physical factors are found only certain areas, so fishing occupation is developed in certain areas only. For example, Dogger banks in Europe or Grand Banks in north eastern part of USA etc.

(v) Agriculture, lumbering, mining and animal husbandry are the primary economic activities found in Europe.
(vi) A star (★) symbol for mining is shown for the production of mining in seas and oceans.
(vii) Mining is not found in the continent of Antarctica.
(viii)The world’s fishing is mostly carried out in the Atlantic Ocean.
(ix) Agriculture, mining, fishing, lumbering and animal husbandry are the primary economic activities found to the south of Tropic of Capricorn.
(x) Agriculture, fishing, and lumbering are the economic activities found in the islands of South East Asia.
(xi) Out of the four continents less agriculture is practiced in the continent of Australia.

(xii) Considering latitudinal extent except North Africa agricultural activities are important economic activities in latitudinal belt 8° to 50° North parallel of latitudes in the northern hemisphere and 20° to 45° latitudes in the southern hemisphere.

• Climate is the most important deciding factors in the development of agriculture.
• With the exception of a few areas, no country in this latitudinal belt experiences snowfall or frost. These weather phenomenon are harmful for the development of agriculture.
• Rainfall in this latitudinal belt is also sufficient and fairly distributed except deserts in continents of Asia and Africa.
• These are all generalised statements. However, agriculture in these latitudinal belts is affected as per the local variations in local weather conditions and physiography of the region.

List out the effects of deforestation on the environment, animals, birds and humans. (Textbook Page No. 35)
Answer:

• For thousands of years man has been using forests for his shelter, food and clothing and therefore, world’s forest resources are gradually diminishing.
• If, too many trees are cut, forest is not capable of re-establishing itself. This may lead to many environmental problems.

Some of the important problems are as follows.

• After deforesting in many areas, a decrease in rainfall could be noticed.
• As a result of rapid deforestation environmental problems like floods, cyclones, soil erosion, tsunami etc., are increasing.
• Due to large scale deforestation in India, 79 species of mammals, 44 species of birds, 15 species of reptiles and 3 species of amphibians are threatened.
• Nearly 1,500 plant species are considered endangered.

Question 1.
With the help of internet, find out about Wild Life (Conservation) Act. (Textbook Page No. 33)
Answer:
Wildlife Protection Act, 1972 and Amendment in 1991.
(i) Objective of the Act is to protect the wild animals, birds and plants particularly the endangered or threatened species.
(ii) The Act prohibits the capturing, killing, poisoning or trapping of wild animals.
(iii) A national wildlife action plan has been made under it.
(iv) The Act envisages the creation and management of sanctuaries and national parks.
(v) A section has also been incorporated for creation of Biosphere Reserves.

The objectives and components of the Act are as follows:

• Control the rapid decline of wildlife. Therefore, specified endangered species are to be protected as a matter of priority.
• In general, protect all species.
• Prohibit regulate hunting (prohibit unlicensed poaching) of wild animals and birds.
• Prohibit regular trade in wild animals, their body parts and articles made by using their body parts.
• Set up protected areas like wildlife sanctuaries and national parks.
• Set up central 200 authorities to regulate zoos and encourage captive breeding of endangered species in the zoos.
• Constitute a wildlife Advisory Board in each state to advice the respective state Governments.

In 1991, the Act was amended to include plants in its definition of wildlife. Until then, for almost two decades, protection of plant life was not on agenda.

Question 2.
Find out how over exploitation of all kinds of animal resources affect human lives and environment. (Textbook Page No. 36)
Answer:

• Due to over exploitation of animal resources there is over grazing and heavy soil erosion.
• Many times, heavy soil erosion results into desertification of land.
• Many times, trees, shrubs and even their roots are used by rural people to feed the animals, it results into deforestation and desertification becomes intense.
• All disadvantages of soil erosion and desertification are faced by human beings.

Question 1.
Observe the given map in fig. (Textbook Page No. 32) and answer the following questions. (Textbook Page No. 34)

(i) Which countries in the monsoon region practice lumbering on large scale.
(ii) In which part of Australia is lumbering carried on?
(iii) Why do you think lumbering is not carried out in the Northern part of Africa?
(iv) Write a note on relationship between latitudes and lumbering.
(v) Why lumbering is not developed on commercial level in Equatorial region?
Answer:
(i) India, Myanmar, Nepal, Cambodia, Vietnam and Philippines.
(ii) In south western and south eastern part of Australia lumbering is carried on.
(iii) Lumbering is not carried in Northern part of Africa because it is covered by Sahara Desert.

(iv) Lumbering is practiced in the areas where forest grows.

• Different types of forest need different rainfall and temperature conditions for growth of trees.
• The temperature and rainfall are related to latitude.
• Monsoon forests grow in areas of moderate temperature and rainfall; thus, they grow in 30°N to 40°N latitude.
• Coniferous forests grow in cool climate so they grow in 50°N to 70°N latitude

(v) Commercial lumbering is not developed in Equatorial region due to following reasons.

• In Equatorial region there dense and mixed forest growth. Land is covered with marshes.
• The trees provide hardwood which is hard to cut and heavy to carry.
• Due to hardwood it has less demand in the world market.
• Hot and humid climate of this region is not suitable for labour.
• Transport facilities are not well developed.
• Traditional methods of lumbering are used.

Question 2.
Observe the map in figure. (Textbook Page No. 32) and answer the questions given below. (Textbook Page No. 35)

(i) Along which bank of North America is Grand bank located?
(ii) Along which coast of South America is the fishing mostly practiced?
(iii) In which part of Australian continent fishing activity developed?
(iv) Fishing is carried on large scale on the western coast of Africa than on the eastern coast of Africa. Give reasons.
(v) Commercial fishing is practiced on the southern coastline of Greenland. Give reasons.
Answer:
(i) Along North-Eastern bank of North America Grand bank is located.
(ii) Along the Western coast of South America fishing is mostly practiced.
(iii) Along South Eastern part of Australian continent fishing activity is developed.

(iv) Along the western coast of Africa, the continental shelf is broad and water is shallow.

• The Guinea and Benguela warm current and Canary cold current meet together near the Western coastline of Africa, so lot of plankton is available.
• The Western coastline is broken so it is suitable for fishing.
• There is more demand for fish along the western coastline because supply of agricultural goods and meat is limited.
• On the eastern coast of Africa, the continental shelf is narrow, water near the coastline is shallow coastline is smooth, limited plankton etc so fishing is not carried on large scale.
• Therefore, fishing is not carried on large scale on the eastern coast of Africa.

(v) The southern coastline is the traditional area of fishing in Greenland.

• The continental shelf of southern coastline is broad and water near the coastline is shallow.
• The southern coastline of Greenland is broken so it is suitable for fishing.
• The West Greenland current flows along the south coastline of Greenland which brings plenty for plankton near southern coastline.
• It is traditional occupation so skilled people are available for fishing.
• The cold climate of Greenland is suitable for fishing.
• The important species of fish caught near southern coastline of Greenland are Greenland Halibut, Atlantic cod, Snow crab, Atlantic Herring etc.

Question 3.
Look at the map in fig. (Textbook Page No. 32) and answer the following questions. (Textbook Page No. 36)

(i) Do you think there is correlation between animal husbandry and grassland?
(ii) In which continent animal husbandry not practiced on large scale?
(iii) In which regions of the world do animal husbandry and agriculture coincide?
(iv) Animal husbandry is found in between which latitude of the world?
(v) In which zone between 30°North to 30°South latitudes, is animal husbandry not found on large scale? What could be the reason behind.
(vi) What could be the reason of concentration of animal husbandry in the eastern part of Australia?
(vii) Why is animal husbandry developed more in the arid regions of the interior of the continents?
Answer:
(i) Yes, there is correlation between animal husbandry and grassland because animals are grazed on grassland.
(ii) In Africa continent animal husbandry not practiced on large scale.
(iii) In North America, Europe and Asia animal husbandry and agriculture coincide.
(iv) Animal husbandry is found between 30° North to 60° North and 30° South to 55° South.

(v) In a zone between 5° North to 5° South latitudes, animal husbandry is not found on large scale. This zone has equatorial climate, so dense forest growth and inhospitable climate and lack of good quality grass are the reasons for no development of animal husbandry in above mentioned zone.

(vi) For the development of animal husbandry, climate is more important factor. In eastern part of Australia, the climate is suitable for the growth of good quality grass, therefore, animal husbandry is more developed.

(vii) The arid regions of interior of the continents receive very low rainfall.

• Only grass grows in low rainfall areas.
• Due to limited water supply, other economic activities cannot be developed.
• Therefore, only animal husbandry can be developed with the help of grass.

Question 4.
Look at the Fig. (Textbook Page No. 32) and answer the following questions (Textbook Page No. 36 and 37)

(i) In which part of the North American continent is mining mainly found?
(ii) Mining activity is located along which coastal side of South America?
(iii) Comparing other primary economic activities, do you think the extent of mining is related to latitude.
(iv) Looking at the concentration of mining in the world, can you relate it with the economic development of the country?
Answer:
(i) Along North Eastern and western coastline of USA and South Western part of Canada.
(ii) Northern, Western and Southern coastline of South America.
(iii) No, the extent of mining is not related to latitude.

(iv) Yes, we can relate mining with the economic development of the country because minerals provide raw material to many industries, especially heavy industries. Therefore, countries rich in minerals have more economic development. For example, the USA, Developed countries of Europe.

Balbharti Maharashtra State Board Class 7 Maths Solutions covers the 7th Std Maths Practice Set 40 Answers Solutions Chapter 10 Bank and Simple Interest.

Bank and Simple Interest Class 7 Practice Set 40 Answers Solutions Chapter 10

Question 1.
If Rihanna deposits Rs 1500 in the school fund at 9 p.c.p.a for 2 years, what is the total amount she will get?
Solution:
Here, P = Rs 1500, R = 9 p.c.p.a , T = 2 years
∴ Total interest = \(\frac{\mathrm{P} \times \mathrm{R} \times \mathrm{T}}{100}\)
= \(\frac{1500 \times 9 \times 2}{100}\)
= 1500 x 9 x 2
= Rs 270
∴ Total amount = Principal + Interest
= 1500 + 270
= Rs 1770
∴ Rihanna will get a total amount of Rs 1770.

Question 2.
Jethalal took a housing loan of Rs 2,50,000 from a bank at 10 p.c.p.a. for 5 years. What is the yearly interest he must pay and the total amount he returns to the bank?
Solution:
Here, P = Rs 250000, R = 10 p.c.p.a., T = 5 years
∴ Total interest = \(\frac{\mathrm{P} \times \mathrm{R} \times \mathrm{T}}{100}\)
= \(\frac{250000 \times 10 \times 5}{100}\)
= 2500 x 10 x 5
= Rs 1,25,000
∴ Yearly interest = Total interest ÷ Time = 1,25,000 ÷ 5 = Rs 25000
Total amount to be returned = Principal + Total interest
= 250000 + 125000 = Rs 375000
∴ The yearly interest is Rs 25,000 and Jethalal will have to return Rs 3,75,000 to the bank.

Question 3.
Shrikant deposited Rs 85,000 for \(2\frac { 1 }{ 2 }\) years at 7 p.c.p.a. in a savings bank account. What is the total
interest he received at the end of the period?
Solution:
Here, P = Rs 85000, R = 7 p.c.p.a., T = \(2\frac { 1 }{ 2 }\) years = 2.5 years
∴ Total interest = \(\frac{\mathrm{P} \times \mathrm{R} \times \mathrm{T}}{100}\)
= \(\frac{85000 \times 7 \times 2.5}{100}\)
= \(\frac{85000 \times 7 \times 25}{100 \times 10}\)
= 85 x 7 x 25
= Rs 14875
∴ The total interest received by Shrikant at the end of the period is Rs 14875.

Question 4.
At a certain rate of interest, the interest after 4 years on Rs 5000 principal is Rs 1200. What would be the interest on Rs 15000 at the same rate of interest for the same period?
Solution:
The interest on Rs 5000 after 4 years is Rs 1200.
Let us suppose the interest on Rs 15000 at the same rate after 4 years is Rs x.
Taking the ratio of interest and principal, we get
∴ \(\frac{x}{15000}=\frac{1200}{5000}\)
∴ \(x=\frac{1200 \times 15000}{5000}\)
= Rs 3600
∴ The interest received on Rs 15000 is Rs 3600.

Question 5.
If Pankaj deposits Rs 1,50,000 in a bank at 10 p.c.p.a. for two years, what is the total amount he will get from the bank?
Solution:
Here, P = 150000, R = 10 p.c.p.a., T = 2 years
∴ Total interest = \(\frac{\mathrm{P} \times \mathrm{R} \times \mathrm{T}}{100}\)
= \(\frac{150000 \times 10 \times 2}{100}\)
= Rs 30000
∴ Total amount = Principal + Total Interest
= 150000 + 30000
= Rs 180000
∴ Pankaj will receive Rs 180000 from the bank.
