Earth’s Constructive & Destructive Forces

3. Earth materials deposited by erosion.
8. A landform made of sediment that is deposited where a river flows into an ocean or lake.
9. Process in which sediment is laid down in new locations.
11. The movement of sand along a beach.
13. The difference in elevation from one contour line to the next.
14. The difference in elevation between the highest and lowest parts of an area.
17. Wind erosion that removes surface materials.
19. Any one of several processes by which gravity moves sediment downhill.
21. A sudden, violent flood that occurs within a few hours, or even minutes, of a storm.
23. A line on a topographic map that connects points of equal elevation.
24. A looplike bend in the course of a river.
25. The process by which water, ice, wind, or gravity moves weathered rock and soil.

1. A process that breaks down rock through
2. Process that splits rock, seeps into cracks, then freezes and expands.
4. The type of weathering in which rock is physically broken into smaller pieces.
5. A large mass of moving ice and snow on land.
6. A wall made of rocks or concrete that is built outward from a beach to reduce erosion.
7. A large stream of moving water that flows through the oceans.
10. Water that flows over the ground surface rather than soaking into the ground.
12. A meander cut off from a river.
15. A deposit of wind-blown sand.
16. Wave-washed sediment along a coast.
18. The grinding away of rock by other rock particles carried in water, ice, or wind.
20. The land area that supplies water to a river system.
21. Wide valley through which a river flows.
22. A long ridge formed by deposits of sediments alongside a river channel.
