Across
  1. 1. a large ridge of material formed from glacial movement pushing eroded material to the sides and front.
  2. 4. a mass of glacier ice that covers terrain and is greater than 50,000 km².
  3. 6. the trapping of heat in the atmosphere from greenhouse gases.
  4. 7. massive chunks of ice that break off of an ice shelf created when continental glaciers flow down towards the ocean.
  5. 10. small lakes formed from blocks of ice calving from glaciers and becoming submerged in sediment on the outwash plain.
  6. 11. marks or lines etched into the sides of valley rocks that can provide scientists with hints of the direction of glacial flow
Down
  1. 2. a sharp ridge from two or more glaciers eroding a mountain from both sides.
  2. 3. a large body of ice formed from the accumulation and compaction of snow that does not completely melt.
  3. 4. is a dome-shaped mass of ice that covers less than 50,000 km² of land area.
  4. 5. an elongated hill formed from rocky debris deposited by glaciers. These hills show the direction the glacier moved in
  5. 8. cracks in the ice that can be hundreds of meters deep.
  6. 9. a ridge created from small river channels flowing beneath the glacier
