Weathering Fast Facts
- Weathering is the mechanical and chemical breakdown of rocks and minerals, eventually creating soils.
- Chemical weathering reactions include carbonation, hydrolysis, oxidation, solution and hydration reactions.
- Biologically produced chemicals, such as those produced by lichens and mosses, can also break down rocks.
