FIVE MARKS QUESTIONS
Question. Explain the resources on the basis of origin and exhaustibility.
Ans : Resources on the basis of origin :
a. Biotic resources : Resources obtained from the environment are called biotic resources. For example-trees, animals and insects.
b. Abiotic resources : Resources obtain from nonliving things present in our environment are termed as abiotic resources. For example-earth, air, water, metals, rocks, etc. Resources on the basis of exhaustibility :
a. 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.
b. Non-renewable resources : Resources which cannot be renewed or reproduced by any physical, chemical or mechanical process are known as nonrenewable resource. For example- water, wind, tidal energy, etc.
Question. 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 :
a. 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.
b. 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. c. 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.
Question. 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 :
a. New and improved equipments are introduced with the development of technology, which ultimately lead to an increase in the use of natural resources.
b. 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.
c. 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.
Question. ‘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 : a. 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.
b. 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.
c. 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.
Question. How can the problem of land degradation be solved ?
Ans : Land degradation has become a major problem today. We have shared our land with the past generations and will have to do with the future generations. There are many ways to solve the problem of land degradation. Afforestation and proper management of grazing can help in solving the problem of land degradation. Planting shelter belts of plants, control on over grazing, stabilisation of sand dunes by growing thorny bushes are also some of the methods to check land degradation. Proper management of waste lands, control of mining activities, proper discharge and disposal of industrial effluents and wastes after treatment can reduce land and water degradation in industrial and suburban areas.
Question. Provide a suitable classification for resources on the basis of ownership. Mention main features of any three types of such resources.
Ans : On the basis of ownership resources can be classified into the following categories :
a. 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.
b. 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.
c. National resources : Resources owned by an individual nation are called national resources. For example -Government land, roads, canals and railways are national resources.
d. 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.
Question. What are the four main factors which help in the formation of soil ?
Ans : The main factors that help in soil formation are :
a. Parent rock : It influences the colour and texture of the soil. The mineral content of the soil also depends on the parent rock from which it is formed.
b. Climate : It influences the rate and types of weathering and erosion of the rocks. Weathering of the parent rocks due to climatic factors and natural forces leads to disintegration of rocks. Subsequently, this leads to the formation of soil.
c. Time : It determines the maturity of the soil. Soil is a living system. It takes millions of years to form soil upto a few centimetres in depth.
d. Relief: This refers to the landscape position and the slopes. Steep and long slopes mean water will run down faster and potentially erode the surfaces of the slopes. The effect will be poor soils on the slopes, and richer deposits at the foot of the slopes.
SOURCE BASED QUESTIONS
Question. At present, there are about 130 million hectares of degraded land in India. Approximately. 28 per cent of it belongs to the category of forest degraded area, 56 per cent of it is water eroded area and the rest is affected by saline and alkaline deposits. Some human activities such as deforestation, over grazing, mining and quarrying too have contributed significantly in land degradation.
Mining sites are abandoned after excavation work is complete leaving deep scars and traces of over-burdening. In states like Jharkhand. Chhattisgarh. Madhya Pradesh and Odisha deforestation due to mining have caused severe land degradation. In states like Gujarat, Rajasthan, Madhya Pradesh and Maharashtra overgrazing is one of the main reasons for land degradation. In the states of Punjab, Haryana, western Uttar Pradesh, over irrigation is responsible for land degradation due to water logging leading to increase in salinity and alkalinity in the soil. The mineral processing like grinding of limestone for cement industry and calcite and soapstone for ceramic industry generate huge quantity of dust in the atmosphere. It retards the process of infiltration of water into the soil after it settles down on the land. In recent years, industrial effluents as waste have become a major source of land and water pollution in many parts of the country.
