Erosion
There are many kinds of Erosion. Here are a few

• Wave Action
• Running Water
• Landslides

• Creep
• Rock Fall
• Mud Flow

• Avalanche
• Glaciers
• Slump

CH14 Erosion and Deposition

• Erosion and deposition The process that moves
  soil and rock and shapes the land.

4
Wave action is when waves hit the rocks and
pieces of rock break off.
5
In this picture the running water eroded the
sides of this canyon and created the V-shaped
valleys.
6
This is a picture of a landslide. A type of mass
wasting.
7
In this picture the land has slumped into the
road below.
8
This is a diagram of creep. The hillside slowly
slips over many years from temperature or water.
9
This is a picture of an avalanche. It is similar
to a landslide with ice and snow instead of rock.
10
This is a picture of a glacier which carves out a
U-shaped valley where it flows dragging rocks and
boulders along the way.

Types

• Surface The physical alteration of the earths
  crust.
• A. Streams and Rivers erode materials, move them
  downstream and deposit them in different
  locations.
• B. A young river has steep slope in its riverbed
