As weathering mechanisms, how does hydration differ from hydrolysis?
What will be an ideal response?
Hydration involves little chemical change in the rock and doesn't form new chemical compounds. However, it does involve a change in the structure of the rock. Hydrolysis is the decomposition of a chemical compound by reaction with water. Hydrolysis chemically breaks down a mineral, thereby producing a different mineral through a chemical reaction.
