Chapter 3 - Erosion and Deposition

1. The force that moves objects downhill.
3. A wind-formed deposit made of fine particles of clay and silt.
5. Time in Earth’s history during which glaciers covered large parts of the surface.
8. The process by which water, ice, wind, or gravity moves weathered particles of rock and soil.
11. A landform made of sediment that is deposited where a river flows into an ocean or lake.
12. A region in which a layer of limestone close to the surface creates deep valleys, caverns, and sinkholes.
13. Water that flows over the ground surface rather than soaking into the ground.
15. An icicle-like structure that hangs from the ceiling of a cavern.
16. Water that fills the cracks and spaces in underground soil and rock layers.
17. Earth materials deposited by erosion.
19. The flat, wide area of land along a river.
22. A column-like form that grows upward from the floor of a cavern.
23. A part of the shore that sticks out into the ocean.
25. Any one of several processes by which gravity moves sediment downhill.
27. A tiny groove in soil made by flowing water.
29. A stream or river that flows into a larger river.
31. A loop-like bend in the course of a river.

2. A long, narrow glacier that forms when snow and ice build up in a mountain valley.
4. A large channel in soil that carries runoff after a rainstorm.
6. A glacier that covers much of a continent or large island.
7. Wave-washed sediment along a coast.
9. A meander cut off from a river.
10. A movement of water and sediment down a beach caused by waves coming into shore at an angle.
11. Process in which sediment is laid down in new locations.
14. A ridge formed by the till deposited at the edge of a glacier.
15. A beach formed by longshore drift that projects like a finger out into the water.
17. A deposit of wind-blown sand.
18. A wide, sloping deposit of sediment formed where a stream leaves a mountain range.
20. Any large mass of ice that moves slowly over land.
21. A small depression that forms when a chunk of ice is left in glacial till.
24. The process by which wind removes surface materials.
26. The sediments deposited directly by a glacier.
28. The process by which a glacier picks up rocks as it flows over the land.
30. A channel through which water is continually flowing downhill.
