Across
  1. 3. A a geomorphological feature, an irregularly shaped hill or mound composed of sand, gravel and till that accumulates in a depression on a retreating glacier, and is then deposited on the land surface with further melting of the glacier
  2. 4. A process whereby portions of a glacier's leading edge break off as icebergs into an adjacent body of water
  3. 8. Chemical reaction of water with other substances
  4. 10. Breakup of rock due to exposure to processes that occur at earth's surface.
  5. 12. Bends or curves in a river channel
  6. 13. A stream valley that has been glaciated, usually to a typical catenary, or U-shaped, cross section
  7. 15. A U-shaped body of water that forms when a wide meander from the main stem of a river is cut off, creating a free-standing body of water
  8. 19. Downslope transportation of large masses of earth by gravity
  9. 21. A depression in the ground formed by a chunk of the glacier that melted after being buried with sediments
  10. 23. Peeling of surface layers from exposed bed rock
  11. 24. Soil layer with physical and chemical properties different than other layers
  12. 26. A long narrow winding ridge consisting of stratified sand and gravel
  13. 27. The process by which sediments are placed onto a surface
  14. 28. A freshwater stream that feeds into a larger stream or river
  15. 29. An ridge of unsorted sediments deposited by a glacier
Down
  1. 1. Top of soil, contains organic materials
  2. 2. A period of long-term reduction in the temperature of Earth's surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers
  3. 5. Weathering away rock material by grinding
  4. 6. A ridge of unsorted sediments deposited by a glacier
  5. 7. Area of land drained by a river
  6. 9. The area around a stream that could drain into the stream
  7. 11. A thick cover of ice over an area, sloping in all directions from the center
  8. 14. An amphitheater valley formed by glacial erosion
  9. 16. Sand and silt deposited along the front of a glacier by the meltwater streams of a glacier
  10. 17. The area along the banks of a meandering river that are prone to flooding at various times
  11. 18. Rain water contains unusually high amounts of acid
  12. 20. A large mass of ice found at high elevations or high latitudes
  13. 22. Removal and transportation of materials by natural agents
  14. 25. Chemical reaction of oxygen with other substances
  15. 27. A teardrop-shaped deposit of sediments re-shaped by a glacier pointing in the direction of glacial movement
