Erosion

Erosion is the natural process which involve the movement of rock fragments through various agents. Over time, this forces can wear down and reshape rocks, changing the Earth's landscape

For example, rivers can and will carve through the earth creating its own path

Deposition

Deposition is the natural process where sediments, sometimes caused by erosion, accumulate in a new location. It's responsible for the formation of sedimentary rocks and it's very important in shaping the Earth’s surface.

For example, you can see the deposition of sand along the shorelines

Weathering

Weathering is the natural process in which rocks wear away or break because of the weather, like rain, snow, etc... Weathering is important in the formation of soil and the creation of unique geological features.

For example, rocks can cut in half because of rain, thunder or snow
