Across
  1. 1. material moves as a whole unit, leaving behind a crescent shaped scar
  2. 4. caused by expanding by freezing water in cracks and crevices
  3. 5. a rock that has been abraded, pitted, etched, grooved, or polished by wind-driven sand like hoodoos and arches
  4. 9. any debris that moves down a slope
  5. 10. break down of rocks due to chemical reactions occurring between the minerals in rocks and the environment
  6. 12. help protect the mainland from erosion caused by wind and ocean waves
  7. 16. occurs when rocks or rock fragments fall freely through the air
  8. 17. process where earthen materials are worn away and transported by natural forces like wind or water
  9. 18. oval-shaped hills, largely composed of glacial drift, formed beneath a glacier
  10. 20. caused by wind picking up suspended particles and hitting solid objects
  11. 21. Wind can create these landforms when it deposits its sediments, especially in deserts and along coasts
  12. 24. physical forces break rock into smaller and smaller pieces without changing rock’s mineral composition
  13. 25. caused by alternating extreme hot/cold temperatures, breaking rock in layers
  14. 26. a thick ice mass that forms above the snowline over hundreds or thousands of years
Down
  1. 2. type of fungus and algae that grow on rocks and produce organic acids which dissolve rock
  2. 3. plants break apart rocks
  3. 6. like dams made to prevent overflow of a body of water
  4. 7. breaking down of rocks and land from forces like gravity, wind, water and ice
  5. 8. long, winding, steep-sided ridges of gravel and sand that are left behind when a glacier melts
  6. 11. process where sediment is deposited by natural forces like wind, water, ice, gravity
  7. 13. When the top of a sea arch breaks and an offshore column of rock remains
  8. 14. sediment carried by a river as it enters slower-moving or stagnant water and creates this landform
  9. 15. mass movements of material containing a large amount of water
  10. 19. Water deposits clay, silt, and sand on the insides of curves but erodes the outer sides of the river channel
  11. 22. enormous ice masses that flow in all directions from one or more centers and cover everything but the highest land. They currently cover Greenland and Antarctica
  12. 23. removal of solid particles by wind.
