2. repeated wetting and drying.
3. oxidation of minerals in a rock
Select the correct answer using the codes given below.
1 and 2 only
1 and 3 only
3 only
1, 2 and 3
Explanation:
Chemical weathering is what happens when rocks are broken down and chemically altered. Frost action and repeated wetting and drying are the process of physical weathering. Oxidation of minerals in rocks by moisture is chemical weathering. Another process of chemical weathering would be decomposition by organic acids
