Answer Keywords

Main Body

Weathering can be defined as disintegration of rocks, soil e.t.c using physical, chemical & biological agents.

Number of process

1Physical weathering : Also called as mechanical weathering & is most common

[Factors involved]

Pressure changes

Temperature changes [exfoliation]

Freez-thaw cycle

Cold wet cycle

Frost wedging (water ice expands)

for eg: Due to repeated cycles of increase and decrease of temperature rocks disintegrate => Sheeting.

2Chemical weathering : It involves losing of bonds.

[Factors] → oxidation & reduction

Hydrolysis

Carbonation (karst topography)

Acidification (Acid rain → TAJ mahal)

Dissolution & solution e.t.c

3Biological weathering : In this living organisms are involved.

Factors → Seeds growing in rock space

Rodents burrowing in soil

Decaying matter releasing Humus

Lichen & mosses → disintegrating rocks

Significance of weathering

Formation of soil

Mineral enrichment by leading

Creation of landforms/hills eroding against.
