The breaking down of rocks, soil and minerals as well as artificial materials through contact with the Earth's atmosphere, animals, plants and waters.

Mechanical Weathering - Running Water

Chemical Weathering - Rock Staining

Biological Weathering - Roots

Three Three Major Types Of Weathering MECHANICAL WEATHERING - Rocks are broken down into smaller pieces without changing their composition. CHEMICAL WEATHERING – Rocks break down as their minerals change in composition. BIOLOGICAL WEATHERING – Rocks that break down both physically and chemically as a direct result of Animals or Plants.
