What evidence is left of the Ice Age?
What is the definition of a Glacier?

3. A. Glacier Definition- A large mass of ice that moves over land.
How do they form? – They form in cold regions when more snow falls than melts each year.

4. B. Discovery Demo
How do Glaciers Affect the Land?

5. Make an Inference
Based on your observations, how do you think moving ice could change the surface of the land?
?????????

6. C. Types of Glaciers
Continental Glacier- a glacier that covers much of a continent or large island.
Valley (Alpine) Glacier- form in mountains and flow down through valleys.

7. D. Glacial Erosion
As glaciers flow over the land they can pick up rocks, including large boulders.
Abrasion- rock remains on the bottom of a glacier and the glacier drags them across the land. This process scratches the bedrock creating striations.
Valley glaciers can change v-shaped mountain valleys into U- shaped valleys with wider, flatter bottoms.

8. E. Glacial Deposition
Till- the unsorted mixture of sediments that a glacier deposits directly on the surface. It consists of particles of varying sizes.
Moraine- till deposits at the edges of a glacier forms a ridge.
Kettle Lake- small depressions that form when a chunk of ice is left in glacial till. When the ice melts it fills the depression creating a lake.

9. E. Glacial Deposition Continued
Drumlin- a long mound of till that is smoothed in the direction of the glaciers flow.
