Across
  1. 2. A crumbly, windblown deposit of silt and clay
  2. 4. Dune A deposit of wind-blown sand that forms in deserts or along coasts
  3. 5. A landform created by sediment deposited where a river meets an ocean or lake
  4. 6. A rapid downhill movement of rock and soil caused by gravity
  5. 7. The grinding away of rock by rock particles carried by wind, water, ice, or gravity
  6. 10. A ridge of sediment deposited at the edge of a glacier
  7. 11. Rain Rainwater mixed with pollutants that causes rapid chemical weathering
  8. 13. A loop-like bend in the course of a river
  9. 14. The uppermost layer of soil, rich in organic material and nutrients
  10. 17. The layer of soil beneath topsoil, containing clay and minerals but little humus
  11. 19. A large mass of moving ice that shapes the land through erosion and deposition
  12. 21. The rapid movement of a large amount of water-saturated soil and debris
  13. 22. The very slow movement of soil downhill due to freezing and thawing
Down
  1. 1. A flat, wide area along a river that floods when water overflows its banks
  2. 3. Lake A small depression formed when a chunk of ice is left in glacial till and melts
  3. 5. The laying down or settling of eroded material
  4. 8. The process that produces rust when oxygen combines with iron in the presence of water
  5. 9. The process that breaks down rock and other substances on Earth's surface
  6. 12. Dark-colored organic material in soil from decayed plant and animal remains
  7. 14. A smaller stream or river that flows into a larger river
  8. 15. Wedging The process of water freezing in cracks of rocks and expanding, causing the rock to break apart
  9. 16. The process by which natural forces move weathered rock and soil from one place to another
  10. 18. The solid layer of rock beneath the soil
  11. 20. The sudden downward slipping of a mass of rock and soil along a curved surface
