Explanation:
- Mechanical weathering involves the breakdown of the rocks into small pieces by the external support such as pressure whereas Chemical weathering involves the breakdown of the rocks takes place by the chemical process.
- Mechanical weathering is a physical change that is caused by the movement of wind and water whereas chemical weathering takes place when the chemicals present in the air or water get mixed with minerals or rocks.
- Mechanical weathering involves:
Abrasion, freezing, thawing, exfoliation.
- Whereas Chemical weathering involves:
dissolution, oxidation, carbonation, hydrolysis.
