Chapter 8 Review - Mass Movement & Glaciers

3. a sorted pile of till that forms when water & sediment fills a depression in the ice, which later melts
6. the rapid movement of dry land, rocks, and soil downslope
10. the slowest form of mass movement; it often isn't noticeable for several years.
11. a type of mass movement in which a single, large mass of solid land moves downhill and rotates slightly.
12. the area of land near the receding edge of a glacier where outwash is often found
15. a glacier that forms on a large, mostly flat area of land near one of Earth's poles
17. a type of glacier movement in which the bottom layer of snow and ice melts, allowing the rest of the glacier to slide over the land below
18. an unsorted pile of till
19. a glacier that moves downslope, usually found in mountainous areas
20. a bowl-shaped depression in the ground/mountainside left by a glacier
21. a type of mass movement in which rocks, soil, and snow moved rapidly downhill

1. the medium-paced, downhill movement of rock, soil, and water (often triggered by earthquakes)
2. the general term for all types of downhill movement of rock, mud, or soil caused by gravity
4. a long, winding trail of outwash left by a river that once flowed beneath the ice in a glacier
5. a type of glacier movement in which solid ice crystals slide over each other
7. the rapid movement of rocks, soil, and water downslope
8. a hole in the ground left by a moving glacier which later fills up with precipitation or runoff
9. a tear-shaped mound of till that forms when a glacier moves over an old moraine
13. Rivers can carve a v-shaped valley in mountains. GLACIERS, however, carve one of these instead.
14. a type of mass movement in which rocks fall down vertically through the air
16. a large, moving mass of snow and ice
