Across
  1. 2. an opening in the Earth’s surface that causes a landform and is caused by divergent and convergent boundaries
  2. 4. caused by the sudden movement from Earth’s crust that results in waves of shaking
  3. 8. type of crust that makes up the sea floor
  4. 11. a type of boundary where the plates slide sideways past each other
  5. 14. a deep hole or also called a ditch in the ground
  6. 15. very hot and dense center of Earth and is below the mantle
  7. 17. occurs along divergent boundaries where new ocean floor is created when the Earth’s tectonic plates spread apart
  8. 19. happens at divergent boundaries and leads to the creation of a newer ocean floor
  9. 24. a flat region where Earth’s tectonic plates move apart
  10. 25. large slabs of rock that divide Earth’s crust
  11. 26. a type of boundary that collides then one plate slides under the other
Down
  1. 1. a supercontinent that was predicted to have broken apart millions of years ago
  2. 3. A crust plate forced beneath another at a plate boundary
  3. 5. a chain of volcanoes that surrounds the Pacific ocean
  4. 6. a landform that’s formed by convergent plates that collide up
  5. 7. he made the theory of seafloor spreading
  6. 9. the way which heat travels
  7. 10. his hypothesis was that the continents had once formed a single landmass called Pangaea before breaking apart and drifting to their current location
  8. 12. largest layer of Earth and is in-between the crust and outer core
  9. 13. the process of continents moving
  10. 16. a type of wave caused by an earthquake
  11. 18. the solid outer part of Earth that consists of the crust and the outer mantle
  12. 20. a small area or region with a relatively hot temperature in comparison to its surroundings
  13. 21. type of crust that makes up the continents on Earth
  14. 22. a type of boundary that moves away from each other
  15. 23. a crack in the Earth’s lithosphere that occurs between two pieces of rock
