Chemical weathering is a process in which rocks erosionate due to chemical reactions:
- High chemical levels: when levels of chemical elements increase for any reason, these can contribute to chemical weathering.
- Humans: the chemicals humans use most of the time penetrate on the earths surface also contributing to chemical weathering.
- Chemical reactions: when certain chemical reactions occur they can oxidate or erode their surroundings contributing to chemical weathering.
