Erosion Land Forms

Moving water causes erosion. The force of water hitting the ground can loosen materials. Moving water carries particles with it.

Runoff Moving water across land.

Rills and Gullies Rill- small groove formed by moving water Gully- larger groove; formed by moving water 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 Alluvial fan-fan shaped deposit of sediments as a moving body of water slows down

Landforms Created by Rivers/deposition Delta-deposit of sediments where a moving body of water enters another body and slows down
