3. Glacier
A large (enormous) mass of ice

4. Alpine Glacier
Glaciers that form in mountainous area.

5. Continental Glacier
Glaciers that are huge and spread across entire continents.

6. Horns
Sharp, pyramid shaped peaks that form when three or more cirque glaciers erode “a” mountain.

7. Cirques
Bowl-shaped depressions where glacial ice cuts back into mountain walls.

8. Aretes
Jagged ridges that form between two or more cirques cutting into the same mountain.

9. Glaciers move by?
The ice underneath the glacier melts but does not drain away thus it builds up beneath the ice. This buildup of melt-water decreases the friction between the glacier and the land below which causes the glacier to flow.

10. U-Shaped Valleys
Forms when a glacier erodes a river valley from its original V shape to a U shape.
