What happens when sediment eroded by water, ice, and wind slows down or stops moving?

• The sediment is deposited in a new location

• The sediment continues to erode

Where do erosion and deposition occur in a river?

• Deposition occurs where fast moving river water picks up soil and moves it downstream. Erosion occurs where a river current slows as it enters a larger body of water and drops the soil.

• A river erodes land. There is no deposition.

• A delta forms at the mouth of a river from depositon. There is no erosion.

• Erosion occurs where fast moving river water picks up soild and moves it downstream. Deposition occurs where a river current slows as it enters a larger body of water and drops soil.

How is water a weathering agent?

• It dissolves minerals in rocks
