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 erodes.

• The sediment instantly turns to soil.

• The sediment mixes with other sediment to become rock.

Where does erosion occur in a river?

• Erosion occurs where fast-moving river water picks up soil and moves it downstream.

• Erosion occurs where the river current slows as it enters a larger body of water and drops soil.

• Erosion occurs when rocks hit against each other in the water.

Deposition from rivers occur when...

• Fast-moving river water picks up soil and moves it

• The river current slows as it enters a large body of water and drops the soil.

• When large river rocks hit against eachother

Chemical weathering happens fastest under what conditions?

• low temperature

• abundant water

• glaciation

• sparce plant growth

How is water a weathering agent?

• it is not a weathering agent

• it grows on rocks and breaks them apart

• it grinds and polishes rocks

• it disolves minerals in the rocks
