Across
- 3. the process by which glaciers flow slowly as grains of ice deform under pressure and slide over each other
- 4. theory that cyclical change in Earth's orbit and in the tilt of the Earth's axis occur over thousands of years and cause climatic change
- 11. a large rock that transported from a distant source by a glacier
- 12. a landform that is made from unsorted sediments deposited by a glacier
- 13. the process that causes the ice at the base of a glacier to melt and the glacier to slide
- 14. a bowl-like depression in a glacial drift deposit
- 16. a long, winding ridge of gravel land coarse sand deposited by glacial meltwater streams
- 17. rock material carried and deposited by glaciers
Down
- 1. 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 surround topograph
- 2. narrow, wedge-shaped mass of ice that forms in a mountainous region that is surrounded by changing topography
- 5. a long period of climatic cooling during which the continents are glaciated repeatedly
- 6. a large crack or fissure that results from in a glacier from ice movement
- 7. a sharp, jagged ridge that forms between cirques
- 8. a sharp, pyramid-like peak that forms because of the erosion of cirques
- 9. a large mass of moving ice
- 10. a deep and steep bowl-like depression produced by glacial erosion
- 15. unsorted rock material that is deposited directly by a melting glacier
