Across
  1. 1. a sudden violent flood that occurs within a few hours or even minutes of a storm
  2. 8. the land area that supplies water to a river system
  3. 9. the type of weathering in which rock is physically is broken into pieces
  4. 11. the process that breaks down rock through chemical changes
  5. 13. the difference in elevation between the highest and lowest parts of an area
  6. 15. Any one of several processes by which gravity moves sediment downhill
  7. 16. the difference in elevation from one contour line to the next
  8. 19. the movement of sand along a beach
  9. 20. water that flows over the ground surface rather than soaking into the ground
  10. 21. Wind erosion that removes surfaced materials
  11. 23. A wall made of rocks or concrete that is built outward along a beach to reduce erosion

  13. 25. A long ridge formed by deposits of sediments alongside a river channel
Down
  1. 2. Wide valley through which a river flows
  2. 3. A rush of water that flows rapidly back to sea through a narrow opening in a sandbar
  3. 4. the process that splits rock when water seeps into cracks, then freezes and expands
  4. 5. Waved washed sediment along a coast
  5. 6. a deposit of windblown sand
  6. 7. Earths materials deposited by erosion
  7. 10. a landform made of sediment that is deposited where a river flows into an ocean or lake
  8. 12. A looplike bend in a course of a river
  9. 14. A large mass of moving ice and snow on land
  10. 17. The process by which water, ice, wind, or gravity moves weathered rock and soil
  11. 18. a line on a topographical map that connects points of equal elevation
  12. 21. Process where sediment is laid down in new locations
