Across
  1. 1. One piece of evidence for continental drift
  2. 4. Where tectonic plates meet and interact
  3. 6. Side effect / result of divergent boundary
  4. 7. Happens to the sea floor; makes new crust
  5. 11. Type of current where hot, less dense items rise and cooler, more dense items sink
  6. 12. Composed of the crust and upper mantle
  7. 13. The mantle is full of this molten rock
  8. 14. Side effect / result of convergent boundary
  9. 15. Scientist in 1912 that proposed Continental Drift
  10. 17. Large pieces of the crust that fit together like puzzle pieces
  11. 18. Geologist in 1960s who came up with Sea Floor Spreading
Down
  1. 2. When a less dense piece of crust plunges below a more dense piece of crust
  2. 3. Coolest layer with the least pressure
  3. 5. State of the rock in the lithosphere
  4. 7. The speed at which tectonic movement happens
  5. 8. Side effect / result of a transform boundary
  6. 9. The once massive super continent
  7. 10. Hottest layer with the most pressure
  8. 13. State of the rock in the mantle
  9. 16. Largest layer of Earth where convection currents happen
