Across
- 3. Beginnings of glaciers. Snow, ice and the freeze- thaw cycle creates armchair-like hollows in the side of a mountain. Over time the hollows grow larger.
- 4. Large ridges of gravel, sand and boulders that were pushed aside by a glacier or dragged to the and of a glacier.
- 7. The downward slope of the ocean floor as it extends outward from the continents
- 11. When glaciers move over uneven ground, ice sheet breaks and produces deep cracks.
- 14. Deep steep sided valleys. Most are formed by rivers slowly cutting their way through the surrounding rock.
- 15. An area surrounded by high- elevation, in which all water runs to a common destination. A large river. Ex.Fraser River
- 17. Large boulder that was carried by glaciers and then left behind on the land when the glaciers receded
- 18. Ocean currents that move in circular patterns
- 19. Masses of ice and snow built up over thousands of years, occur in the high altitudes of mountains, and near the Earth's poles. Lower layers are turned into ice because of the weight of the snow above.
Down
- 1. A large chunk of ice that breaks off a glacier when the glacier reaches the ocean
- 2. An underwater volcano
- 5. Long,snake-like mounds of sand and gravel that mark the path of meltwater streams that passed through under a glacier.
- 6. When lava builds up, cools and forms an island. ex.Hawaii
- 8. Large flat areas on the ocean floor. Most of the ocean bottom
- 9. Where a small glacier meets a large glacier. Its like a small half pipe going into a big one.
- 10. Inlets in the coast with steep walls. Caused by glaciers moving.
- 12. Movement in the water.
- 13. Run parallel to the coast, are formed when two oceanic tectonic plates converge.
- 16. 3 or more arêtes that carve into a mountain peak into a sharp pyramid shape
- 19. Once a volcanic island, it has been eroded and the volcanic island has been covered by the ocean
- 20. Two cirques on a mountain that erode toward each other and create a sharp ridge between them.
