Question

How is soil formed? Short points

Answer 1

Hey dear,

➡ Big stone boulders break into small stones by natural processes like rain, harsh weather, roots of trees etc. This process of breaking of rocks into smaller pieces is known as weathering.

➡These small pieces of rocks are carried by river and further made into small pebbles and then to sediments.

➡ These sediments change to soil and settle at the bank of rivers.

Hope this helps you... : )

Answer 2

The process involving the origin, development and formation of soil is known as pedogenesis.

For millions of years there was continuous breaking of rocks into small particles due to heat, rain and wind.

These small particles were carried away by wind and water and ultimately got deposited over other rocks. In this way, thick layer of clay, sand and small pieces of rocks are formed. This is known as soil.

The process of soil formation is known as weathering. Weathering is the process of disintegration of parent rocks into smaller particles (regolith). The weathering basis of agents can be classified as

(a) Physical weathering

(b) Chemical weathering
