Answer :The main techniques that can be used to control soil erosion in the hilly areas are given below-
|Biotic resources||Abiotic resources|
|These are obtained from biosphere.||All those things which are composed of non-living things are called abiotic resources.|
|Examples are human beings, flora and fauna, fisheries, livestock.||Examples are rocks and metals.|
Answer :The use of land is determined both by physical factors such as topography, climate, soil types as well as human factors such as population density, technological capability and culture and traditions etc. The pattern of the net sown area varies greatly from one state to another. It is over 80 per cent of the total area in Punjab and Haryana and less than 10 per cent in Arunachal Pradesh, Mizoram, Manipur and Andaman Nicobar Islands. Forest area in the country is far lower than the desired 33 per cent of geographical area, as it was outlined in the National Forest Policy (1952). It was considered essential for the maintenance of the ecological balance. A part of the land is termed as wasteland and land put to other non-agricultural uses. Wasteland includes rocky, arid and desert areas and land put to other non-agricultural uses includes settlements, roads, railways, industry etc. Continuous use of land over a long period of time without taking appropriate measures to conserve and manage it has resulted in land degradation.
Large scale production leads to over utilization of resources as more and more raw sources are required.
(i)Natural endowments in the form of land, water, vegetation and minerals.
(ii)A type of non-renewable resource.
(iii)Soil with high water retaining capacity.
(iv)Intensively leached soils of the monsoon climate.
(v)Plantation of trees on a large scale to check soil erosion.

Answer :The State of Madhya Pradesh is richly endowed with mineral wealth. It is the sole producer of diamond in the country. Coal, limestone, manganese ore, bauxite, copper ore, dolomite, fire clay, slate pyrophyllite-diaspore are the main minerals occurring in the State.
Answers :The net sown area and the land under forests have changed from 1960-61 to 2002-03 very marginally because of the following factors:
Answers :Net sown area in Arunachal Pradesh, Mizoram and Manipur is low mainly due to the hilly and rocky terrain. Andaman and Nicobar Islands are covered by dense tropical forests and so net sown area is low.
