The wearing away and moving of weathered rock and soil:

• oxidation

• sediment

• erosion

Sediment that is carried by agents of erosion is eventually dropped in a process called:

• deposition

• weathering

• sediment

List causes of erosion:

• hurricanes, mud, glaciers

• rivers, waves, glaciers, wind, and gravity.

• evolution, gravity, mud
