Across
  1. 3. interlocking spur eroded by a glacier
  2. 4. plucked rocks are stuck in the base of the glacier as it moves the rocks scrape and smooth the surface they pass over
  3. 5. when a few ribbon lakes are linked
  4. 6. huge sheets of ice covering areas of the earths surface
  5. 7. narrow, steep sided ridge usually between two cirques
  6. 9. the friction between the ice and ground creates heat causing the ice at the base to melt. The meltwater gets in the cracks of the rocks and freezes. When the ice moves again in plucks the rock out
  7. 10. hollow on side of a mountain. Birthplace of a glacier
  8. 13. lake inside a cirque
  9. 14. a v-shaped valley straightened and flattened by a glacier
  10. 15. steep-sided mountain eroded by many cirques
Down
  1. 1. warmer periods during the ice age
  2. 2. when ice sheets cover large areas of the earths surface
  3. 8. tributary valley hanging above the main glaciated valley
  4. 11. ice begins to move to lowland areas under the influence on gravity
  5. 12. weather conditions in an area measured over a long period
