What Is Chemical Weathering? - ThoughtCo

Chemical weathering does not break rocks into smaller fragments through wind, water, and ice (that's physical weathering). Nor does it break rocks apart through the action of plants or animals (that's biological weathering). Instead, it changes the chemical composition of the rock, usually through carbonation, hydration, hydrolysis or oxidation.

Hydrolysis is a type of chemical weathering, which includes oxidation, reduction, carbonation, solution, and hydration. If water and a compound meet together, hydrolysis is the reaction that occurs.

Chemical Weathering - ScienceStruck

Sep 26, 2018· When weathering takes place as a result of chemical reactions, it is known as chemical weathering. In this process the rock disintegrates chemically as the chemicals in the atmospheric agents react with the chemicals of the rock and the resultant reaction brings about the weathering of the rock.

Weathering of Rocks: Physical and Chemical | Geology

ADVERTISEMENTS: After reading this article you will learn about the physical and chemical weathering of rocks. Mechanical Weathering or Physical Weathering: Mechanical or physical weathering refers to changes involving form only.
