2. Mechanical Weathering
Exfoliation
Ice Wedging
Organic Activity
Abrasion

3. Exfoliation
Slabs of outer rock to break off in layers

4. Ice Wedging
The mechanical breakup of rock caused by the expansion of freezing water in cracks and crevices

5. Organic Activity Organic weathering:
Organic weathering involves organic acids produced by plant organisms. The acids attack rock-forming minerals.

6. Abrasion
The process of wearing down or rubbing away by means of friction.

7. Acid- carbonation, precipitation, and plant acid
Chemical Weathering
Hydrolysis
Oxidation
Dissolution
Acid- carbonation, precipitation, and plant acid

8. Hydrolysis
Decomposition of a chemical compound by reaction with water, such as the dissociation of a dissolved salt or the catalytic conversion of starch to glucose.

9. Oxidation
Oxidation is the process whereby oxygen combines with compounds in some rocks. Oxidized iron forms rust.

10. Dissolution
The dissolving of a material in a liquid.
