Front

What is physical weathering?

Back

Physical weathering is the breaking down of rocks into smaller pieces without changing their chemical composition.

Front

How do landslides relate to erosion and deposition?

Back

Landslides erode dirt and rock and deposit them in new locations as they move.

Front

What is the role of wind in erosion?

Back

Wind can erode surfaces by carrying away loose particles and sand, especially in dry areas.

Front

What is a delta?
