Type of Soil Erosion
    Water erosion
    Wind erosion
    Gravitical erosion
    Frozen-melt erosion
     Water Erosion

   Sheet erosion
   Rill erosion
   gullies or gully erosion
Water Erosion----- Rill erosion
Water Erosion----- gullies or gully erosion

 Gullies are larger than rills
  and cannot be fixed by
  tillage. Gully erosion is an
  advanced    stage    of   rill
  erosion, just as rills are
  often the result of sheet
  erosion.
                 Wind Erosion

Wind erosion, unlike water,
 cannot be divided into such
 distinct types. Surface texture
 is the best key to wind
 erosion hazard potential.
          Gravitical Erosion

Gravity   is   the    principal
 force    acting     to   move
 surface materials such as
 soil and rock.
   Frozen-melt Erosion
A particularly mysterious form of frost
 damage is frost heave, resulting in
 damaged roads, buildings and cropland.
 As can be expected, frost heave works
 with the strength of frost.
