Question

soil is formed by water if u agree with this statement give reason

Answer 1

Role of water in soil formation Rocks on earth’s surface are not chemically stable and constantly undergo the process of weathering. It is the first step of soil formation. Chemical weathering involves the breakdown of primary minerals in the rock to new minerals that are more stable in the surface environment. Water is the essential agent in chemical weathering. It either reacts directly with the minerals or carry dissolved species which themselves react with the mineral.

Answer 2

1. Water helps in formation of soil in the following ways:
2. Water wears off the rocks over a long period of time.
3. Small rocks in the flowing water rub against other rocks creating small particles which are carried away downstream and deposited as soil.
4. Water expands on freezing. So when it is deposited in crevices of rocks, rocks crack into smaller pieces.
