Across
  1. 4. Tectonics/ The theory of that the earth's surface is broken into plates that slide over the magma in the mantle
  2. 6. the point below the surface where the earthquake started
  3. 7. of fire A large connection of volcanoes that form the edge of the Pacific plate
  4. 8. lines
  5. 11. Drift The slow movement of of continents over the mantle
  6. 13. Smaller earthquake after major earthquake
  7. 14. Wave A wave that vibrates threw the earth that is produced by earthquakes and volcano eruptions
  8. 16. Boundary A boundary at where plates collide into each other
  9. 17. of the earth that is water
Down
  1. 1. crust and the rigid part of the mantle's surface
  2. 2. boundary A boundary at where plates slide past each other,no crust in made or destroyed (lots of earth quakes happen here)
  3. 3. rock for the mantle
  4. 5. A crack or break in rock
  5. 8. lines
  6. 9. Boundary A boundary at where plates move apart and new crust is formed
  7. 10. An instrument that records the energy of the earthquake vibrations
  8. 12. The point directly on top of the surface where the earthquake started
  9. 15. Spreading/The moving apart of plates on the ocean floor
  10. 18. A super continent that existed 200-300 million years ago when all plates were connected
  11. 19. Wagner/A German scientist that proposed that there was one a super continent called pangea
