Science
Chemical weathering.
Definition
Chemical weathering is the breakdown of rocks through chemical reactions that alter the mineral composition of the rock. Common processes include oxidation, hydrolysis, carbonation, and acid reactions with minerals.
Examples
Real-world.
- 1 Iron in rocks reacts with oxygen and water to form rust (iron oxide), weakening the rock
- 2 Acid rain dissolves limestone and marble statues through carbonation reactions
- 3 Feldspar in granite undergoes hydrolysis to form clay minerals
