Across
- 2. Water that fills the cracks and spaces in underground soil and rock layers
- 4. The sediments deposited directly by a glacier
- 7. A landform made of sediment that is deposited where a river flows into an ocean or lake
- 8. Water that flows over the ground surface rather than soaking into the ground
- 9. The flat, wide area of land along a river
- 14. A long, narrow glacier that forms when snow and ice build up in a mountain valley
- 16. The geologic principle that the same geologic processes that operate today operated in the past to change Earth's surface
- 17. Process in which sediment is laid down in new locations
- 18. The process by which a glacier picks up rocks as it flows over land
- 20. Dark-colored organic material in soil
- 22. A wide, sloping deposit of sediment formed where a stream leaves a mountain range
- 23. Time in Earth's history during which glaciers covered large parts of the surface
- 25. A glacier that covers much of a continent or large island
Down
- 1. The process that breaks down rock through chemical changes
- 3. The process by which water, ice, wind, or gravity moves weathered particles of rock and soil
- 5. The movement of water and sediment down a beach caused by waves coming in to shore at an angle
- 6. Any one of several processes by which gravity moves sediment downhill
- 7. The process by which wind removes surface materials
- 10. a wind-formed deposit made of fine particles of clay and silt
- 11. The type of weathering in which rock is physically broken into smaller pieces
- 12. Any large mass of ice that moves slowly over land
- 13. Small, solid pieces of material that come from rocks or the remains of organisms; earth materials deposited by erosion
- 15. The loose, weathered material on Earth's surface in which plants can grow
- 19. A stream or river that flows into a larger river
- 21. A deposit of wind-blown sand
- 24. A channel through which water is coninually flowing downhill
