(ii) What type of soil is found in the river deltas of the eastern coast? Give three main features of this type of soil.
Answer :
Alluvial soil is found in the river deltas of eastern coast.
Main features of alluvial soil are –
1. The alluvial soil consists of various proportions of sand, silt and clay.
2. As we move inlands towards the river valleys, soil particles appear some what bigger in size. In the upper reaches of the river valley i.e. near the place of the break of slope, the soils are coarse. Such soils are more common in piedmont plains such as Duars, Chos and Terai.

3. Alluvial soils as a whole are very fertile.
4. Mostly these soils contain adequate proportion of potash, phosphoric acid and lime which are ideal for the growth of sugarcane, paddy, wheat and other cereal and pulse crops.
5. Soils in the drier areas are more alkaline and can be productive after proper treatment and irrigation.

(iii) What steps can be taken to control soil erosion in the hilly areas?
Answer :
Ways to control soil erosion in hilly areas –
1. Contour ploughing : Ploughing along the contour lines can decelerate the flow of water down the slopes. This is called contour ploughing.
2. Terrace Farming : Steps can be cut out on the slopes making terraces. Terrace cultivation restricts erosion. Western and central Himalayas have well developed terrace farming.
3. Strip Farming : 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. This method is known as strip cropping.

4. Shelter Belts ( desert areas not hilly areas ) : Planting lines of trees to create shelter also prevent soil erosion. Rows of such trees are called shelter belts. These shelter belts have contributed significantly to the stabilisation of sand dunes and in stabilising the desert in western India.

(iv) What are the biotic and abiotic resources? Give some examples.
Answer :
Biotic Resources: All those things obtained from biosphere and have life are known as biotic resource . For example : human beings, flora and fauna, fisheries, livestock etc.
