What are some agents of erosion?

Back

Water, wind, ice, and gravity are the main agents of erosion.

Front

What is deposition?

Back

Deposition is the process where eroded materials are dropped off in a new location.

Front

How does erosion change the landscape?

Back

An example of weathering is flood water pounding against a canyon wall and wearing it down.
