Here's how it works:
* Water acts as a solvent and interacts with the minerals in the rock.
* Chemical reactions occur, breaking down the mineral structure.
* This process often leads to the formation of new minerals, which are usually softer and weaker than the original minerals.
Example: Feldspar (a common mineral in rocks) can undergo hydrolysis to form clay minerals. This process weakens the rock and makes it more susceptible to other forms of weathering.
Other types of chemical weathering:
* Oxidation: Reactions with oxygen, often causing rusting.
* Carbonation: Reactions with carbonic acid, which dissolves minerals like limestone.
* Biological weathering: Chemical reactions caused by living organisms.
