Glaciers shape the earth due to a process called EROSION 

Erosion: the movement of the earth’s surface from one location to another

  • Continental Glacier: Spreads itself out using it’s own weight
    • Expand existing rivers and lakes (The Great Lakes)
  • Alpine Glacier: Found in mountainous areaseeaecf3c-318f-4691-88e9-fd7cf36817fb
    • Creates a U-shaped valley with moraine at the base
  • Moraine: a mass of rocks and sediment carried down and deposited by a glacier, typically as ridges at its edges or extremity.
