  3. 9. the sudden and rapid movement of a large amount of material downslope
  4. 12. the major agent of erosion that shapes our land surface
  5. 13. the mostly solid, rocky part of the Earth
  6. 15. the process by which the outer layers of rock slowly peel away due to pressure changes
  7. 16. the frozen water on Earth
  8. 17. the part of the Earth that is liquid water
  9. 19. rock that is formed when magma or lava cools and hardens to become solid
  10. 21. rock formed when pressure or temperature change existing rock
  11. 22. ice _______ can cause rocks to physically break apart
