Here's how it works:
* Water as a solvent: Water is a powerful solvent and can dissolve many minerals found in rocks. This process is called dissolution. For example, limestone is dissolved by acidic rainwater, creating caves and sinkholes.
* Hydrolysis: Water reacts with minerals in rocks, breaking them down into new minerals. This is called hydrolysis. For instance, feldspar, a common mineral in granite, can be hydrolyzed into clay minerals.
* Oxidation: Water can also promote oxidation, a process where minerals react with oxygen. This is common with iron-containing minerals, leading to the formation of rust.
So, while water is a crucial component in several types of weathering, it specifically drives chemical weathering through these chemical reactions.
