WED PUZZLE

4. occur when individual rock fragments abruptly break off the sides of a steep cliff after exposure to gradual weathering, such as by exfoliation
9. modifies a smooth slope into a series of level, stair-like steps; erecting windbreaks out of trees, tall plants, or fences
11. When soil rushes down a mountain dangerously
12. physical processes like wind or running water that carry away the rock fragments
13. involves the breaking or peeling away of rock in
16. The eroded rock fragments are eventually set down (deposited) in a new location
17. the breakdown of large rocks into fragments by physical forces, such as ice, rapid changes in temperature, and grit carried by wind and running water

1. When minerals in rock react chemically with air
2. rapid movements of water saturated soil
3. The process in which gravity causes the downslope movements of rock, soil, volcanic ash,
5. process by which rocks are broken down by the forces of nature
6. base of the mountain or cliff, the broken fragments collect in huge piles of rock
7. A mass of ice and snow abruptly dislodging from
8. long piles of rocks deposited parallel to the shore
10. mountain face
14. water, the minerals may weaken or even dissolve away, causing the rock to crumble
15. occurs when rainwater or melted ice soaks into tiny cracks in a rock and freezes; the sudden expansion of the ice as it freezes can split the rock
