Question 47
“Soil is formed by water.” If you agree to this statement then give reasons.

Answer 1

Water helps in the formation of soil in the following ways:
(i) Water causes ‘wear off’ of rocks over a long period of time.
(ii) It also causes the rocks to rub against other rocks creating small particles which are taken away downstream and deposited as soil.
(iii) Water expands on freezing in crevices of rocks and cracks rocks into smaller pieces.
