Across
  1. 3. until the middle of 1900, people believed that the continents were where they are since the earth was made
  2. 4. These borders are highly active geological zones where the Earth's crustal plates interact
  3. 6. Are two tectonic plates collide one plate will subduct or go under the other
  4. 7. the instrument that records earthquake
  5. 9. is a big study of how the earth plants move
  6. 14. Has a upper and lower layer around earth
  7. 15. is a old artefact that is buried underneath ground for years
  8. 16. one tectonic plate dives beneath another and sinks into the Earth's mantle
  9. 18. a fracture in the Earth's crust where rock masses have shifted relative to each other
  10. 19. Are two tectonic plates slide past each other
  11. 21. A long, narrow, and elevated surface that drops off on both sides
  12. 22. is steep elevated caused convergent boundaries
Down
  1. 1. unit used to determine core strength of the earthquake
  2. 2. It happens when two plates release stored energy along the fault
  3. 5. drift: earth continents move and where once joined together
  4. 6. it is a outer layer around earth
  5. 8. The believe that all the continents move together
  6. 10. Is a large deep hole in the ground
  7. 11. when intense heat inside the Earth melts rock into magma
  8. 12. the scale to measure earthquakes
  9. 13. is the center of earth and is solid from pressure
  10. 17. the outer shell of the earth slowly move around
  11. 20. Are two tectonic plates moving apart from rising magma
