Three features of alluvial soil are:

- The regions of alluvial soils are intensively cultivated and densely populated.
(iii) In hilly areas, soil erosion can be controlled by ploughing across contour-lines, making use of terrace farming techniques and using strips of grasses to check soil erosion by wind and water.
(iv) Biotic Resources: The resources which are obtained from the biosphere and have life are called Biotic Resources. For example, animals and plants including human beings.
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?
(ii) How have technical and economic development led to more consumption of resources?
Answer: (i) Land resources in India are primarily divided into agricultural land, forest land, pasture and grazing land, and wasteland. Wasteland includes rocky, arid and desert areas and land used for non-agricultural purposes like housing, roads, industry, etc.
According to recent data available, the percentage of net sown area (NSA) in India is about 54% of the total reporting area (if, the other than current fallow lands is included). 22.5% is covered by forests, and 3.45% is used for grazing. The rest is a wasteland, with traces of miscellaneous cultivation.
Improper use of forest land has led to land degradation and made conservation of forests difficult. Human activities like deforestation, overgrazing, mining, quarrying, etc have contributed to the slow growth rate of forests. Thus, land under forest has increased by only about 4% since 1960-61.
(ii) Technical and economic development have led to more consumption of resources on account of various factors such as:
- Technological development provides sophisticated equipments. 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 favourable environment for the development of latest technologies. It helps to make or convert various materials found around us into resources. Finally, it results into the consumption of new available resources too.
