Erosion Land Forms

Moving water causes erosion.The force of water hitting the ground

can loosen materials.Moving water carries particles with it.

Both of these only carry water after it rains

Stream and Rivers

Stream-Rarely dry up, continually moving water (creeks)

Rivers- larger body of moving water.

Runoff- 5 factors

Amount of water available Vegetation Soil Type Land shape Influence of populations

In general, more runoff, more erosion.

Landforms Created by Rivers/deposition

Delta-deposit of sediments where a moving body of water enters another body and slows down
