Across
  1. 2. the middle layer of the earth.
  2. 3. The mechanical model; lithosphere, asthenosphere, mesosphere, outer core, inner core. (look at me on ice)
  3. 5. a boundary where the plates move away from eachother
  4. 6. the outer layer of the core.
  5. 9. a divergent boundary where new crust is formed in the ocean
  6. 12. the theory that the continents are always moving.
  7. 14. the cracked-up parts of earths crust.
  8. 15. when something is pressed together.
  9. 16. the center of the earth.
  10. 17. the 3rd mechanical layer
  11. 18. the 1st mechanical layer
Down
  1. 1. the theory of plates moving on the asthenosphere
  2. 4. when the plates slide past eachother
  3. 7. what something is composed of.
  4. 8. when the plates come together.
  5. 9. when one plate (usually the denser, oceanic plate) go under another.
  6. 10. A long rigid crack in the earths surface.
  7. 11. the inner layer of earths center
  8. 12. the very outer layer of the earth.
  9. 13. the 2nd mechanical layer
