Weathering is any process that breaks down rocks and creates sediments. There are two forces of weathering, chemical and mechanical (physical).
Chemical weathering is decomposition of rock caused by chemical reactions resulting in formation of new compound.
Mechanical (physical) weathering is the breakdown of rock into smaller pieces.
Erosion is the process by which natural forces move weathered rock and soil from one place to another. Gravity, running water, glaciers, waves, and wind all cause erosion. The material moved by erosion is sediment.
Deposition occurs when the agents (wind or water) of erosion lay down sediment. Deposition changes the shape of the land.
