Weathering comes from weather, which means "bad weather". Temperature changes also act in this process.

Also known as weathering, weathering is the set of mechanical, chemical and biological processes that cause the disintegration and decomposition of rocks.

The decomposed rock turns into a material called a mantle or regolith.

In the case of mechanical (or physical) disintegration, rocks may break without changing their composition. In the deserts, temperature variations eventually break the rocks, as well as in cold zones, where water seeps into the cracks in the rocks.
