35.
Explain any three human activities responsible for land degradation in India.
[2013, 2012]
or
How are human activities responsible for the degradation of land?
[2012]
Ans :
- Mining: Mining sites are abandoned after excavation work is complete leaving deep scars in states such as Jharkhand, Chhattisgarh, Madhya Pradesh and Odisha. Deforestation due to mining has caused severe land degradation.
- Over irrigation: Over irrigation in the states of Punjab, Haryana, western Uttar Pradesh, has caused water logging and increase in salinity of soil.
- Overgrazing: Overgrazing in states such as Gujarat, Rajasthan, Madhya Pradesh and Maharashtra is a huge cause due to cattle population
- Industries: Mineral processing industry like grinding of limestone for cement industry and calcite and soapstone for ceramic industry generate huge quantity of dust. This retards the process of infiltration of water into the soil.
- Industrial waste: Industrial effluents also have become a major source of land degradation.
36.
Suggest any three methods of soil conservation suitable to Indian conditions.
[2012]
or
What steps can be taken to control soil erosion in hilly areas?
[2012]
Ans :
Methods of soil conservation:
- Ploughing along the contour lines can decrease the speed of water flow down the slopes.
- Step or terrace cultivation on slopes restricts erosion. Western and Central Himalayas have well-developed terrace farming.
- Strip cropping: Here large fields can be divided into strips. Strips of grass are left to grow between the crops. This breaks up the force of the wind.
- Shelter belt plantation: Trees are planted in rows. These shelter belts have led to the stabilisation of sand dimes and in stabilising the desert in western India.
37.
What is meant by the term “resource”? List the types of resources classified on the basis of its ownership.
[2012]
Ans :
- Resource: Everything available in our environment which can be used to satisfy our needs, provided, it is technologically accessible, economically feasible and culturally acceptable is known as a resource.
- Types of resources on the basis of ownership are: Individual, community, national and international.
38.
Distinguish between the renewable and nonrenewable resources.
[2012]
Ans :
- Renewable resources: Resources which can be renewed or reproduced by mechanical, physical or chemical processes are known as renewable or replenishable resources, e.g., solar and wind energy, water, forests and wildlife, etc.
- Non-renewable resources : These occur over very long geological times. Minerals and fossil fuels are examples of such resources. These resources take millions of years in their formation. Some of the resources like metals are recyclable and some of them such as fossil fuels cannot be recycled and get exhausted with their use.
39.
Distinguish between stock and potential resource. Give one example of each.
[2012]
Ans :
| Stock | Potential resources: |
|---|---|
| 1. They are found in the environment. | They are found in a region. |
| 2. They are not accessed due to the lack of technology. | They have not been utilized or developed. |
| 3. Example: Water is a compound of two 1 inflammable gases— hydrogen and oxygen, which can be used as a rich source of energy. But we do not have the required technical know- how to use them for this purpose. | Example: Rajasthan and Gujarat have enormous potential for the development of wind and solar energy but they are yet to be developed for various reasons. |

- Climate breaks the parent rock into small pieces.
- Vegetation: Plant and animal organisms help in the weathering of the rocks slowly but continuously
- Various forces of nature such as change in temperature, actions of running water, wind and glaciers, activities of decomposers, etc., contribute to the formation of soil.
- Chemical and organic changes take place in the soil.
42.
Which geographical factors are responsible for the evolution of black soil? Why is it considered the most suitable for growing cotton?
[2012]
Ans :
- Climatic conditions along with present rock material are important factors for making of black soil. The parent rock is volcanic rock.
- It is ideal for growing cotton because of the following reasons:
- It has capacity to hold moisture.
- It is rich in soil nutrients such as calcium carbonate and potash.
- Deep cracks in the soil help in aeration.
43.
Mention any two human activities which are responsible for the process of soil erosion. Explain the two types of soil erosion mostly observed in India?
[2012]
Ans :
Two human activities which are responsible for the process of soil erosion are deforestation and overgrazing, mining, construction, etc.
Types of Soil Erosion :
- Gullies: The running water cuts through the clayey soil and makes deep channels/gullies. The unfit land caused by gullies is called bad land or ravines.
- Sheet erosion: water flows as a sheet over large areas down a slope. The top soil is washed away.This process is known as sheet erosion.
44.
Differentiate between stock and reserve stating two points of difference.
[2011]
Ans :
- Stock: Materials, which have the potential to satisfy human beings but human do not have the appropriate technology to access these, are termed as stock. We do not have the required technical ‘know-how’ to use them for a specific purpose, e.g., water which is a compound of two inflammable gases hydrogen and oxygen and can be a rich source of energy. We do not know how to use them.
- Reserves: These are subset of the stock. They can be put into use with existing know-how but their use has not been started. For e.g., river water is used as a source of hydroelectricity but to a limited extent. Thus, the water in the dams, forests, etc., are reserves which can be used in the future.
45.
Explain the types of resources on the basis of exhaustibility with the help of examples.
[2011]
Ans :
- Renewable resources: Resources which can be renewed or reproduced by mechanical, physical or chemical processes are known as renewable or replenishable resources, e.g., solar and wind energy, water, forests and wildlife, etc.
- Non-renewable resources: These occur over very long geological times. Minerals and fossil fuels are examples of such resources. These resources take millions of years in their formation. Some of the resources like metals are recyclable and some of them such as fossil fuels cannot be recycled and get exhausted with their use.
46.
What are the three stages of resource planning in India?
Ans :
[2012, 2011]

51.
Explain resource planning. What are the steps involved in resource planning?
[2014]
or
Why is resource planning essential in India?
[2015]
or
What is resource planning? Why is resource planning essential? Explain it with three reasons.
[2015]
Ans :
Resource planning is a procedure of proper utilisation of resources. Resource planning is important because :
- Resources in India are not evenly distributed. Some parts of the county are rich in one resource but deficient in other important resources which are essential. For example, Rajasthan is rich in solar and wind energy but lacks water resource. Jharkhand is rich in minerals and coal deposits but lack in industrialisation. This is the reason why resource planning is essential. An effective resource planning will help in effective use of the resources available in the environment.
- Secondly, most of the resources present in our environment are limited. Therefore, if these resources are not preserved or not used rationally we will be in great trouble. For example : Petrol is a limited resource and it cannot be renewed. Exhaustion of petrol will create huge chaos in the country as we are extensively dependent on the petrol.
- Thirdly, resource planning is important because it minimises the wastage or over utilisation of resources. The very first step of resource planning is to make a list of resources available in the environment. This helps us to assess which resources should be used and how much it should be used to prevent over utilisation and minimise wastage.
52.
Provide a suitable classification for resources on the basis of ownership. Mention main features of any three types of such resources.
Ans :
[2014]
On the basis of ownership resources can be classified into the following categories :
- Individual resources : Resources owned by a person or an individual are called individual resources. For example-land owned by farmers, and houses are individual resources.
- Community resources : Resources owned by a particular community or a society are called community owned resources. For example- Graveyard, grazing land, ponds, burial grounds and park ark community owned resources.
- National resources : Resources owned by an individual nation are called national resources. For example -Government land, roads, canals and railways are national resources.
- International resources : Resources regulated or governed by an international body are called international resources. For example-Ocean and sea beyond 200 km of the exclusive economic zone belongs to open sea or ocean. No individual country can utilise these resources without the permission of international bodies.
53.
Explain the resources on the basis of origin and exhaustibility.
Ans :
Resources on the basis of origin :
- Biotic resources : Resources obtained from the environment are called biotic resources. For example-trees, animals and insects.
- Abiotic resources : Resources obtain from non- living things present in our environment are termed as abiotic resources. For example-earth, air, water, metals, rocks, etc.
Resources on the basis of exhaustibility :
- Renewable resources : The resources which have the ability to renew them over period of time or can be reproduced by physical, chemical or mechanical processes are known as renewable resources. For example-solar and wind energy, water, forest and wildlife, etc.
- Non-renewable resources : Resources which cannot be renewed or reproduced by any physical, chemical or mechanical process are known as non- renewable resource. For example- water, wind, tidal energy, etc.
54.
List the problems caused due to indiscriminate use of resources by human beings.
Ans :
Resources are essential for human survival. Initially, people believed that the resources are the free gift of nature. Therefore, they continuously exhausted the resources available in the environment without taking any preventive measures. As a matter of fact, they faced economic, social and ecological problems.
The major problems that cropped up due to over-exploitation, irrational consumption and indiscriminate use of resources are :
- Exhaustion of resources : Due to over exploitation and irrational consumption, the resources exhausted at a rapid pace leaving very little or nothing for the future generation.
- Concentration of resources : Concentration of resources in a few hands is also a major issue. The people with the maximum resources will use them for their own benefits leaving others empty handed. This will create a situation of have and have nots. This situation of have and have nots is unfavourable for the growth of the country as a whole.
- Global ecological crisis : Global warming, depletion of ozone layer, population and land degradation are global ecological crises. This crisis situation is also an after effect of irrational or over utilisation of resources.
55.
How do technical and economical developments led to more consumption of resources?
Ans :
These days, technical and economical developments gain a colossus space. The government is also focusing more on technical and economical growth to make our county a fully developed country. In this process of technical and economical growth, the resources of our country are exhausting rapidly. Technological and economical developments have led to such rapid consumption of resources because of the following reasons :
- New and improved equipments are introduced with the development of technology, which ultimately lead to an increase in the use of natural resources.
- The technological advancement is attributed to the growth of a developing country. People of an economically developing nation consume more resources. Hence, we can safely say that an improvement in economic development of a nation will directly result in the increase of its people’s consumption of resources.
- Development of new technologies is widely seen in developing economies. Due to economic development, the bright minds get an opportunity to experiment with their ideas. As a matter of fact, various materials are converted in to useful resources. This creates an atmosphere, which will see a steady increase in consumption of such available resources.
56.
‘Consumption of energy in all forms has been rising all over the country. There is an urgent need to develop a sustainable path of energy development and energy saving’. Suggest and explain any three measures to solve this burning problem.
Ans :
Energy is an essential requirement for economic development. The strategy of economic development that India has adopted since independence necessarily required increasing amount of energy consumption. As a result, consumption of energy in all forms has been rising. To take care of this concern, various measures that need to be adopted are as follows :
- We need to increase the use of renewable energy resources like solar, wind power, biogas, tidal energy and geothermal energy. This will decrease the dependence on non-renewable sources.
- We have to adopt a cautious approach for judicious use of our limited energy resources. F or example, as a concerned citizen we can use public transport system in place of an individual vehicle.
- Another measure that needs to be adopted is promotion of energy conservation, e.g., switching off electrical devices when not in use, using power saving devices. Thus, consumption of energy in all forms has been rising all over the country.
57.
What is meant by ‘Land Resource’?
Ans :
We live on land and it satisfies our needs in all the possible ways. Land resource, thus is, of much importance for us which includes forests, mountains, plains, plateaus and islands. These support natural vegetation, wild life, economic activities, and transport and communication systems. Therefore, it is necessary for us to use these resources in a wise manner and with careful planning, we should develop holistic and ecological approach towards economic development without compromising the ability of resources to future generations to meet their needs. Though we have the right to meet our present needs by consuming natural resources, we should not deprive the future generations from it.
58.
Explain land use pattern in India and why the land under forest not increased much since 1960-61.
Ans :
Land in India has been divided into different categories with reference to usage. Different categories of land are:
- Farming land which is
