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