2. Desert ____ The coarse surface left behind in areas of intense wind erosion (the finer surface material is removed by winds).
10. A large mass of moving ice on land.
11. Thick layered deposits of wind-blown silt.
15. These type of glaciers are much larger but much rarer than valley glaciers. They were even larger during the ice age.
17. Rocks ____ when wind-blown sand particles rub against the surface of the rocks.
18. Rock that has been shaped by the abrasion of wind-blown sediments.
19. This agent of erosion can move only the very smallest of sediments.
20. A landslide in which earth material rotates and slides along a curved surface.
22. The steep, pyramid-shaped peak formed when a there are glaciers on three or more sides of a mountaintop.
23. Long, winding ridges of layered sediments that are deposited by streams flowing under a melting glacier.
24. The type of glaciers that form in mountainous areas. Sometimes called alpine glaciers.
28. A deep depression carved out by an alpine glacier.
29. An low, elongated hill produced when glaciers move over older moraines.
30. Swiftly moving mixture of mud and water.
31. The bouncing motion of wind-blown sand particles.
32. This kind of moraines forms at the lower (or outer) end of a glacier.
1. A tributary valley that enters a U-shaped valley from high up on a mountain side.
3. The mixed debris that glaciers carry embedded in their ice and on their tops, sides, and front edges. When a glacier melts, this material is deposited.
4. A pile of wind-blown sand.
5. Ridges consisting of till deposited by glaciers.
6. ____ movement. A downslope movement of loose sediment and rock under the influence of gravity.
7. These most common sand dunes are solitary, crescent-shaped dunes that form in flat areas where there is little sand or vegetation.
8. ____ hole. When a buried ice block melts, it leaves behind this depression.
9. A large crack in the top part of a glacier.
12. ____ plain. The area at the leading edge of the glacier, where the meltwater streams flow and deposit sand and gravel.
13. Where two glaciers join together, their lateral moraines combine to form this kind of moraine.
14. The slow, steady, downhill flow of loose, weathered earth materials.
16. Moraines that form along the sides of a valley glacier
19. This acts as a lubricant between grains of soils and sediments.
21. These extremely curved sand dunes form in areas with moderate winds and some vegetation. They are common on seacoasts.
25. The sharp, steep, knife-edged ridge formed where two cirques on opposite sides of a valley meet.
26. A rapid, downslope slide of earth materials.
27. The lowering of the land surface that results from the windís removal of surface particles.
