  • Cirque: Starting location for mountain glaciers
  • U shaped trough or valley U-shaped valleys are created by mountain glaciers, when filled with ocean water.
  • Arete spiky high land between two glaciers, if the glacial action erodes through, a spillway forms.
  • Hanging valley an abrupt change in the longitudinal slope of a glacial valley
  • A horn results when glaciers erode three or more aretes, usually forming a sharp-edged peak. 
  • A moraine is formed on the side of a glacier.  it tears off rock and soil from both sides of its path. This material is deposited as lateral moraine.

    A landslide is formed from weathering and erosion on soil that  allows gravity to pull it all down a slope.
    A flow is an intrusion of molten rock or magma that occurs with crystal accumulation.
    A slump occurs when a coherent mass of loosely consolidated materials or rock layers moves a short distance down a slope. 
    A fall is a high speed collection of rocks that go down at a vertical angle, and when these rocks hit the bottom they fragment forming a talus.
