Question Q2GS1GS1
Weathering is a complex phenomenon involving number of process & is influenced by multiple factors. Explain
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 rainTAJ mahal)
Dissolution & solution e.t.c
3Biological weathering : In this living organisms are involved.
FactorsSeeds growing in rock space
Rodents burrowing in soil
Decaying matter releasing Humus
Lichen & mossesdisintegrating rocks
Significance of weathering
Formation of soil
Mineral enrichment by leading
Creation of landforms/hills eroding against.
Weathering along with erosion and mass wasting regularly change the face of earth surface.
