Across
- 2. / the process that causes the ice at the base of a glacier to melt and the glacier to slide
- 5. / a land-form that is made from unsorted sediments deposited by a glacier
- 6. / unsorted rock material that is deposited directly by a melting glacier
- 8. / rock material carried and deposited by glaciers
- 10. / a large rock transported from a distant source by a glacier
- 12. / a massive sheet of ice that may cover millions of square kilometers, that may be thousands of meters thick, and that is not confined by surrounding topography
- 14. / in a glacier, a large crack or fissure that results from ice movement
- 16. / a bowl-shaped depression in a glacial drift deposit
- 17. / a sharp, pyramid-like peak that forms because of the erosion of cirques
Down
- 1. theory / the theory that cyclical changes in Earth's orbit and in the tilt of Earth's axis occurs over thousands of years and cause climatic changes
- 3. age / a long period of climatic cooling during which the continents are glaciated repeatedly
- 4. / a narrow, wedge-shaped mass of ice that forms in a mountainous region that is confined to a small area by surrounding topography
- 7. / the process by which glaciers flow slowly as grains of ice deform under pressure and slide over each other
- 9. / a large mass of moving ice
- 11. / a deep and steep bowl-like depression produced by glacial erosion
- 13. / a sharp, jagged ridge that forms between cirques
- 15. / a long, winding ridge of gravel and coarse sand deposited by glacial melt-water streams
