Across
  1. 1. boundary a place where two plates slip past each other, moving in opposite directions
  2. 4. Rocks forming due to heat and pressure
  3. 7. One plate going under another plate
  4. 11. Rock Formed from compaction and cementation of sediments
  5. 12. crust the relatively thick part of the earth's crust that forms the large landmasses.
  6. 13. Rock Formed from the crystallization of magma
  7. 14. The breaking down of rocks
  8. 15. The layer of hot, solid material between Earth's crust and core.
  9. 18. The process of moving broken rock (sediment) from one place to another
  10. 21. Going in different directions
  11. 24. The soft layer of the mantle on which the tectonic plates move
  12. 26. an important part of something, a characteristic
  13. 27. A naturally occurring solid mixture of one or more minerals or organic material
  14. 28. Earth's outermost layer.
  15. 30. crust thinner, more dense, younger crust making ocean floor
Down
  1. 2. Valley A deep valley that forms where two plates move apart
  2. 3. ridge The longest underwater mountain chain in the world.
  3. 5. Includes sand, pebbles, bones, and shells
  4. 6. A break in the earth's crust
  5. 8. coming together
  6. 9. drift The hypothesis that the continents slowly move across Earth's surface.
  7. 10. tectonic A theory stating that the earth's surface is broken into plates that move.
  8. 16. one thickness above or between other thicknesses
  9. 17. Center of the earth
  10. 18. proof
  11. 19. Layers found in sedimentary rock
  12. 20. A rigid layer made up of the uppermost part of the mantle and the crust.
  13. 22. Being forced to the surface
  14. 23. Cycle The process in which rocks undergo change
  15. 25. Rock Formed from heat and pressure
  16. 29. A deep, steep-sided canyon in the ocean floor.
