Across
- 6. An ice smoothed rock with its steeper side facing down valley. The resistant rock remains after ice abrasion on the ice-direction facing side and plucking on the lee side.
- 10. A small, deep, circular lake - found in the base of a corrie which has been deepened by abrasion. They filled with water after the Ice-Age.
- 11. A steep cliff like valley side - valley glaciers have removed the ends of interlocking spurs by abrasion.
- 13. Moraine: Material carried within the ice. It may have fallen down a crevasse, be plucked or abraded off the valley sides OR just have been buried by new snow.
- 15. Moraine: Eroded material that is dragged along the base of the glacier and then deposited over a wide area on the valley floor as the ice melts. It creaks a hummocky valley floor.
- 18. Stepped long profile in a glacial trough - formed in the main valley often where 2 glaciers meet.
- 20. Material: The debris deposited from the meltwater produced by a glacier in the spring and summer which acts like a normal river. Its deposition is smooth, round, sorted and stratified.
- 21. The name given for all material deposited by ice, e.g. Morain, Drumlins and Crag and Tails. It is also known as boulder clay and is unsorted, angular and unstratified.
- 24. An amphitheatre (arm-chair) shaped depression in a mountains side with a steep back wall and a rock lip. Formed by frost shattering on the back wall. Deepened by abrasion and steepened by plucking.
- 26. Abrasion can break down rock into something which is carried in meltwater streams for very long distances and is very fine. It also gives the meltwater streams a milky blue/white colour.
- 28. These something based ice sheets are stuck to their bed. They flow by internal deformation only. This is when ice crystals within the glacier slide over each other. Erosion is more limited.
- 29. Moraine:Material carried at the base of the glacier. It has been plucked or abraded from the valley floor. It is also known as ground moraine.
- 30. Moraine: A series of ridges parallel to the terminal moraine.
- 31. Moraine: A crescent shaped ridge which builds up at the snout (end) of the glacier marking the furthest point reached by the glacier.
- 32. The side of a drumlin that is tapered, pointed and gently sloping.
Down
- 1. A tributary glacier left high above the main valley. Ice in the main valley eroded more rapidly than ice in the tributary valleys - often producing a waterfall from the tributary valley.
- 2. A steep sided U-shaped valley which is widened and deepened by erosion from a valley glacier.
- 3. Rocks scarred with thin parallel scratches - englacial or subglacial moraine dragged over rock and ice as it moves. Shallow scratch marks.
- 4. It is a large mass of resistant rock which creates a hill (crag) with a tapering ridge (tail) on its lee. They range in scale from tens of metres to km in length with the tail pointing in the down-glacier direction.
- 5. A pointed summit of a mountain where three or more corries have formed.
- 7. Moraine: Material carried on top of the glacier (e.g. lateral and medial moraine).
- 8. A long mound of till (oval shaped hill) that is smoothed in the direction of the glacier's flow.
- 9. Narrow, knife-edged ridge. Where 2 corries erode back towards each other.
- 12. The end of a drumlin that is round, blunt and steep.
- 14. When bits of rock get stuck in the ice and grind against the rock below the glacier wearing it away. Much of the debris comes from freeze-thaw weathering.
- 16. A landscape that used to have glaciers in but no longer does, e.g Cumbria.
- 17. Moraine: A ridge running in the middle of the valley. It is formed when two lateral moraines meet.
- 19. Occurs when meltwater at the base, back or sides of a glacier freezes onto the rock. As the glacier moves forward it pulls (plucks) pieces of rock out. Meltwater enters the joints in the rock where it refreezes, expands and weakens the rock.
- 22. Deep scratch marks.
- 23. These something based valley glaciers are lubricated by meltwater at their base and so slide easily. They move more quickly which is important for erosion.
- 25. Moraine: A ridge running along the edge of the glaciated valley. It is carried at the edge of the glacier.
- 27. A long, narrow lake in the bottom of a glacial trough. Erosion on the valley floor creates a hollow which fills with water after the Ice-Age.
