Introduction

Weathering is the process of disintegration of rocks due to physical and chemical actions. It is one of major geological process in rock cycle.

Main Body

Physical weathering impacting chemical weathering

1Formation of cracks and joints (eq) water seep into fissures and from ice expanding and causing rock disintegration
2High temperature variations leading to faster chemical actions (eq) frost wedding and unfolding
3[illegible]

chemical weathering prompting in supporting physical weathering

1Oxidation of rocks leading to reduced chemical bonds facilitating physical weathering
2Carbonation due to rainwater leading to small cavity and further rode disintegration in alternate season. (eg) Moving rain have H2O5 reducing rode and next winter iron cavities

[diagram showing rainwater reducing rode to permeabke rode by solution, leading to opening and closing of cavities due to daily heat variation]
