Made when sand and mud gets laid down in layers and eventually turn into layers of rock

The process occurs when the agents of erosion lay down sediment in a new location

• weathering

• erosion

• deposition

This involves the breaking down of large rocks and minerals into smaller and smaller pieces.

• weathering

• erosion

• deposition

This is a process that takes the weathered material formed during weathering and moves those sediments from one place to another.
