Across
  1. 4. the major agent of erosion that shapes our land surface
  2. 6. this gas makes up the majority of the atmosphere
  3. 8. these are fertile, flat areas that are formed when a stream floods and a layer of sediment is deposited
  4. 12. the amount of energy through Earth's system forms an energy ____________
  5. 13. the process by which the outer layers of rock slowly peel away due to pressure changes
  6. 14. the process by which sediment comes to rest
  7. 16. the mostly solid, rocky part of the Earth
  8. 19. rock that is formed when magma or lava cools and hardens to become solid
  9. 20. the part of the Earth that is liquid water
  10. 21. the breaking down and wearing away of rock material by the mechanical action of other rock
  11. 22. rock formed when pressure or temperature change existing rock
  12. 24. the process by which water, wind, ice and changes in temperature break down rock
  13. 26. the place where land and a body of water meet
  14. 28. the sudden and rapid movement of a large amount of material downslope
  15. 30. type of weathering when acid rain breaks down and changes the rock
  16. 33. this is the source of the majority of Earth's energy
  17. 34. this is made up of living things
Down
  1. 1. the rising of regions of the crust to higher elevations
  2. 2. an underwater or exposed ridge of sand, gravel, or shell material
  3. 3. ice _______ can cause rocks to physically break apart
  4. 5. a rapid movement of a large mass of mud
  5. 7. the water located within the rocks below
  6. 9. the sinking of regions of the crust to lower elevations
  7. 10. rock composed of minerals formed from solutions or sediments from older rock
  8. 11. mounds of wind-deposited sand
  9. 15. the process by which other chemicals combine with oxygen
  10. 17. the process by which rock is broken down into smaller pieces by physical changes
  11. 18. the gases that surround Earth
  12. 23. this is known as molten rock
  13. 25. an increase in ________________ gases can increase Earth's temperature over time
  14. 27. the process by which sediment is moved from one place to another
  15. 29. a large mass of moving ice that forms by compacting snow by natural forces
  16. 31. thick deposits of windblown, fine-grained sediment
  17. 32. the slow movement of material downslope
  18. 34. an area of shoreline that is made up of material deposited by waves and currents
