  • Wind erosion damages land and natural vegetation by removing soil from one place and depositing it in another.

  • Two types of wind erosionare deflation, where the wind picks up and carries loose soil particles; and abrasion, where surfaces are worn down as they are struck by airborne particles carried by wind.

  • Landslides can occur when moisture builds weight from heavy rainfall, flooding, rapid snow melting, glacier melting, and an increased water table can cause a landslide. 

  • Landslides take place when dirt, pebbles, rocks and boulders slide down a slope together.

  • Landslides can be very large, involving the entire side of a mountain.

  • Ice Erosion: The movement of glaciers eroding by abrasion and scouring of a surface.

  • In the abrasion process, debris in the ice scrapes along the rock surface, polishing and gouging the underlying rocks, bedrock breaks off and flows with the ice.

  • Coastal erosionis the wearing away of land and the removal of beach by wave action, tidal currents, wave currents, or drainage

  • Waves, Waves, generated by storms, wind, or fast moving motor craft, cause coastal erosion,

  • Rain splash erosion is caused by the impact of water striking the surface.

  • The impact of multiple rain drops hitting the surface splash particles away from the point of impact.
