Across
  1. 4. break down of rocks due to the glacier
  2. 6. Material carried by a glacier.
  3. 7. Moraine found on top of the glacier
  4. 9. breakdown of rocks due to weather/air exposure
  5. 10. Moraine found at the bottom of the glacier
  6. 13. Type of till dropped by a moving glacier
  7. 14. a frozen river of ice that flows downhill under gravity.
  8. 15. Moraine found within the glacier
  9. 16. Type of till dropped by a melting glacier
  10. 18. Percentage which water expands by when it freezes
Down
  1. 1. Ice freezes around the rock. When the glacier flows down, it pulls the rock down with it.
  2. 2. movement of rocks
  3. 3. Zone of _______ = bottom of the glacier where temperatures are higher. Ice melts, shrinking the glacier.
  4. 5. Zone of______ = top of the glacier. Snow falls and compresses into ice, adding to the glacier.
  5. 8. rocks being dropped
  6. 11. Material dropped by a glacier
  7. 12. _______-Thaw weathing
  8. 17. Sandpaper effect. Rocks carried in the ice scrape away the rock underneath.
