Across
  1. 5. Hill of till that is shaped like half an egg
  2. 6. Unsorted debris of varying sizes deposited directly by the glacier (not water)
  3. 9. knob Rock outcrop reformed by a glacier - with one side that is smooth and the other jagged due to rocks being plucked out as the glacier moved forward
  4. 11. plain Expansive flat area in front of a glacier when it is retreating, where sediments are deposited by meltwater (often dominated by braided rivers)
  5. 12. Series of glaciations and interglaciations (warm periods). Several of these have happened over Earth’s history.
  6. 14. Huge boulder in the middle of nowhere that was clearly deposited by a glacier
  7. 17. Scrapes, scratches, and grooves formed in bedrock as glacier dragged rocks and other objects as it advanced
  8. 18. Glaciers found at high altitudes
  9. 19. A winding deposit of sand and gravel from meltwater running through a glacier
  10. 20. aka Continental glacier
  11. 21. Bottom end of a glacier
  12. 23. The name of the last ice age
Down
  1. 1. Formed from a large chunk of ice that was dropped and melted
  2. 2. Granular, compacted snow that has passed through one summer melt season
  3. 3. Glacier found at high latitudes that covers large areas (over 50,000 km2) and flows out in all directions
  4. 4. Crescent-shaped gouges chipped out of bedrock due to a rock or other object being dragged along
  5. 7. The name of the ice sheet that covered most of Canada in the last ice age
  6. 8. Large mass of ice made up from compacted & re-crystallized snow that flows under its own weight on land.
  7. 10. Ridges or mounds of till deposited at the ends and sides of glaciers as they retreat
  8. 13. Characteristic shape of a valley that has been shaped by a glacier
  9. 15. Area of a glacier where snow is removed by melting and sublimation
  10. 16. Deep crack in the top, brittle ice of a glacier
  11. 22. line Line above which snow remains all year (aka line of equilibrium, firn line)
