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