Across
- 2. / unsorted rock material that is deposited directly by a melting glacier
- 4. / a mass of rocks and sediment carried down and deposited by a glacier, typically as ridges at its edges or extremity
- 6. / the process that causes the ice at the base of a glacier to melt and the glacier to slide
- 7. / a long, narrow, steep-sided ridge of coarse sand and gravel deposited by a stream flowing in or under a melting sheet of glacial ice
- 10. / rock material carried and deposited by glaciers
- 11. / 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
- 12. / the process by which glaciers flow slowly as grains of ice deform under pressure and slide over each other
- 14. / a large rock transported from a distant source by a glacier
- 15. / in a glacier, a large crack or fissure that results from ice movement
Down
- 1. / a large mass of moving ice
- 3. / a depression in a glacial out-wash drift made by the melting of a detached mass of glacial ice
- 4. / the theory that cyclical changes in Earth's orbit and in the tilt of Earth's axis occur over thousands of years and cause climatic changes
- 5. / a long period of climatic cooling during which the continents are glaciated repeatedly
- 8. / a narrow, wedge-shaped mass of ice that forms in a mountainous region that is confined to a small area by surrounding topography
- 9. / a sharp, pyramid-like peak that forms because of the erosion of cirques
- 13. / a deep and steep bowl-like depression produced by glacial erosion
- 16. /a sharp, jagged ridge that forms between cirques
