1. Glacier Terms

2. Alpine vs. Continental Glaciers
Glacier: A large mass of compacted snow and ice that moves under the force of gravity
Alpine (Valley) Glaciers: A glacier that moves within valley walls
Continental glacier: a glacier that covers a large part of a continent

3. Glacial Polish
Bedrock surface smoothed by the passage of a glacier

4. Striations
Parallel scratches on the surface of a rock caused by the movement of a glacier- aligned in the same direction as ice flow (ex. if the striation runs north to south, the glacier went from north to south)

5. Drumlins
Oval-shaped mound of unsorted glacial till- The round end of the hill faces the direction that the glacier came from

6. Moraine
Irregular, hilly, unsorted deposit formed at the end of an advancing glacier when the melting ice front stays at the same position for a long time (ex. Long Island)

7. Kettles/Kettle Lake
8. Kettle: Low spots in glacial deposits and places where large, buried ice blocks melt- leaves a hole 9. Kettle Lakes are when the holes fill in with water

8. Erratics
A large boulder dropped by ice

9. Esker
A ridge made by water deposition within a tunnel under the ice

10. Kame
Deltas deposited by the water at the edge of a glacier

11. In Notes: Valley Shape Young riVers make V-shaped valleys
Alpine glaciers make U-shaped valleys

12. Visualizations Seasonal Migration of Snow
Observe the retreat of ice sheets from North America.
Observe how glaciers erode bedrock surfaces.
