Abiotic Resources: The resources which are composed of non-living things are called Abiotic Resources. For example, water, minerals, metals, wind, solar energy etc

 3. Answer the following questions in about 120 words.

(i) Explain land use pattern in India and why has the land under forest not increased much since 1960-61?


Land resources in India are primarily divided into agricultural land, forest land, and meant for pasture and grazing, and wasteland. Wasteland includes rocky, arid and desert areas and land used for other non-agricultural purposes such as housing, roads and industry. According to the recent data, about 54% of the total land area is cultivable or fallow, 22.5% is covered by forests, and 3.45% is used for grazing. The rest is a wasteland, with traces of miscellaneous cultivation.
The land under forest has not increased since 1960–61 because in the post-independence era demand for more land to expand agriculture, mainly after Green Revolution, developmental works and infrastructural facilities, led to clearance of forests areas.Industrialisation and urbanisation also decreased the forest area.Thus, land under forest has increased by only about 4% since 1960-61.


(ii)  How have technical and economic developments led to more consumption of resources?


Technical and economic development has led to more consumption of resources on account of various factors such as

  • Technological development provides sophisticated equipment. As a result, production increases ultimately leading to consumption of more resources.
  • Technological development also leads to economic development. When the economic condition of a country rises, the needs of people also rise. It again results into more consumption of resources.
  • Economic development provides a favourable environment for the development of latest technologies. It helps to make or convert various materials found around us into resources. Finally, it results in the consumption of newly available resources too.



  1. Have a discussion in class how to conserve various resources used in your school

Ans. We have to need to conserve the resources which are used in our school like the water and also the electricity and also the fuel etc. we need to conserve all our limited resources because these types of natural resources are in the limited category. If he does not use them carefully they will last at a near time. so we have to conserve our resources we can do this by using a bicycle for school and to take a bus to school and switch off the fan in the classroom if it is not in use and also conserve the wastes of water by closing the water pipe in the garden or park so from this or from so many ideas, we can conserve the natural resources which are given by nature which also lasts for some time so we need to conserve them or use them carefully. this helps us to conserve our natural resources
