Answer:
Oxidation (a type of chemical weathering)
Explanation:
Chemical weathering is defined as the process by which rocks are disintegrated into smaller particles by chemical reactions. There are different types of chemical weathering and the presence of materials i.e. acids, oxygen, water, and carbon dioxide in rocks can change the minerals found in different rocks. Oxidation is a type of chemical weathering which involves the reaction of oxygen with a substance. Oxidation is also the process that causes rusting of material. If a rock contains iron, it can also undergo oxidation (i.e. rust).
