Chemical Weathering
Types
Organic Action
-
The action of bacteria and the respiration of plant roots tend to increase carbon dioxide levels which helps accelerate solution processes, especially carbonation.
-
-
Hydration
When two surfaces of a body of water and a compound meet. Water is composed of the mineral ions +H and -OH= Deformation of rocks into new compounds
physio-chemical process as rocks swell and exert pressure furthermore changing their chemical structure
Oxidation
So when a rock gets oxidized, it is weakened and crumbles easily allowing the rock to break down.( Iron oxide is brownish red in colour)
Oxidation is the reaction of a substance with another substance. It is also the process that causes rust.
Rocks can get rusty when they contain iron. When iron reacts with oxygen, it forms iron oxide which is not very strong.
Factors
-
-
Vegetation & Relief
The presence of vegetation can increase weathering through release of organic acids through the growth of root systems

Peltier's Diagram
-
The efficiency of weathering is influenced by critical temperature changes, frequency cycles, and diurnal and seasonal variations in temperature
