  1. Erosion Land Forms

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

  3. Runoff • Moving water across land.

  4. 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

  5. Stream and Rivers • Stream-Rarely dry up, continually moving water (creeks) • Rivers- larger body of moving water.

  6. Runoff- 5 factors • Amount of water available • Vegetation • Soil Type • Land shape • Influence of populations • In general, more runoff, more erosion.

  7. Landforms Created by Rivers/deposition • Alluvial fan-fan shaped deposit of sediments as a moving body of water slows down

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

  9. Identify the following by term • meander • gully • rill • stream

  10. Identify the following by term • oxbow • meander • alluvial fan • delta

  11. Identify the following by term • oxbow • meander • alluvial fan • delta

  12. How will this affect runoff? • Large amount • Moderate amount • Small amount

  13. How will this affect runoff?
