Question

“Soil is formed by water.” Justify.

Answer 1

Water helps in formation of soil in the following ways:

(i) Water wears off the rocks over a long period of time.

(ii) Small rocks in the flowing water rub against other rocks creating small particles which are carried away downstream and deposited as soil.

(iii)Water expands on freezing. So when it is deposited in crevices of rocks, cracks rocks into smaller pieces.
