Across
- 3. ice sheets covered huge areas of the earth
- 5. great river of ice
- 8. when ice moves forward it plucks large chunks out of the ground
- 10. weather conditions in an area measured over a long period
- 13. glaciers melted while others joined together
- 14. small tributary valley that hangs above main glaciated valley
- 15. narrow steep sided ridge between two cirques
- 16. as rocks move they scrape and smooth the surface
Down
- 1. v-shaped valley straightened and flattened by glacier to become u-shaped
- 2. interlocking spur whose head was eroded based glacier moved through the valley
- 4. steep sided mountain eroded by cirques
- 6. ice begins to move slowly to lowland areas under the influence of gravity
- 7. during the ice age there are warmer periods
- 9. lake inside a cirque
- 11. lakes when a narrow lake occupies the floor of a valley and when ribbon lakes are linked
