Weathering, Erosion & Deposition

The earth's surface can be changed in three main ways. These processes are called weathering, erosion, and deposition. The first process known as weathering is when the surface is broken down. This can happen through a river or any other form of water-carving rock. The wind blows sediment up against rock to break it down. Or through the ice, expanding to crack The Rock.

The second process is called erosion, which is when the sediment that has been broken down is carried away. This can happen through water, such as a river carrying the sediment, or wind, carrying the sediment through the air. Or from the ice such as a glacier dragging the sediment along the bottom of it. The final process is deposition. This is when the sediment is dropped in a new area.

This can happen at the base of a river. It could happen from a glacier melting and leaving the sediment deposited, or it could happen from when the wind stops blowing, and the sediment becomes deposited. Those are the three processes that help shape the surface of the earth. Weathering, erosion, and deposition.
