Across
  1. 2. when sediment is carried from one location and dropped in another location
  2. 9. the breaking down of rocks or other materials on the earth
  3. 10. these are changed over millions of years by weathering and erosion
  4. 11. when water that falls as precipitation seeps into the ground
  5. 16. large chunks of ice that cause erosion and carry sediment to new locations
  6. 17. weathering that involves hot and cold temperatures making rocks exoand and contract
  7. 18. a type of weathering that occurs between rocks and minerals
  8. 21. rain, snow, hail or sleet that falls from clouds once clouds become to large and heavy
  9. 23. a type of weathering that involves living things liek trees roots or animals breaking up landforms
  10. 24. when water vapor cools and turns back into water in the air forming clouds
  11. 25. large freshwater collections of water that build up over time
Down
  1. 1. when water freezes and expands causing rocks to break apart
  2. 3. materials that are picked up by water or wind and carried to other locations altering landforms
  3. 4. when pressure on top of rocks is relieved the rocks expand and crack
  4. 5. large collections of water droplets in the air that form after condensation
  5. 6. water changing from liquid to vapor and rising into the air
  6. 7. when wind or water carries particles that then rub against other surfaces causing changes to land forms
  7. 8. a type of weathering involving water and ice breaking up rocks
  8. 12. water evaporating from plants into vapor
  9. 13. when water gathers into large pools like lakes or oceans
  10. 14. when salt deposits from water build up in rocks and eventually break the rocks apart
  11. 15. large collections of saltwater
  12. 19. when weathered material is carried away by water from one place to another
  13. 20. a type of erosion that involves gravity when rocks or other materials fall and smash
  14. 22. large underwater pools of freshwater that occur as a result of infiltration
  15. 26. a substance produced by a mix of air and water and minerals that can wear away rocks as part of chemical weathering
