Chemical Weathering Definition, Processes and Types

Types of Chemical Weathering. The various types of chemical weathering arise since it is driven by gradual and ongoing chemical reactions, mineralogy changes, the dissolving of the particles, and then the final wearing away or disintegration of the rocks. These reactions include hydrolysis, carbonation, dissolution, and oxidation.
