Plate Tectonic Vocab

2. a landform that’s formed by convergent plates that collide up
5. a chain of volcanoes that surrounds the Pacific ocean
7. largest layer of Earth and is in-between the crust and outer core
9. a type of wave caused by an earthquake
10. a supercontinent that was predicted to have broken apart millions of years ago
12. A crust plate forced beneath another at a plate boundary
13. a crack in the Earth’s lithosphere that occurs between two pieces of rock
15. type of crust that makes up the sea floor
17. happens at divergent boundaries and leads to the creation of a newer ocean floor
19. the way which heat travels
20. the process of continents moving
21. a type of boundary that collides then one plate slides under the other
24. he made the theory of seafloor spreading
25. type of crust that makes up the continents on Earth
26. a flat region where Earth’s tectonic plates move apart

1. an opening in the Earth’s surface that causes a landform and is caused by divergent and convergent boundaries
3. large slabs of rock that divide Earth’s crust
4. a type of boundary that moves away from each other
6. occurs along divergent boundaries where new ocean floor is created when the Earth’s tectonic plates spread apart
8. the solid outer part of Earth that consists of the crust and the outer mantle
11. a small area or region with a relatively hot temperature in comparison to its surroundings
14. very hot and dense center of Earth and is below the mantle
16. his hypothesis was that the continents had once formed a single landmass called Pangaea before breaking apart and drifting to their current location
18. a deep hole or also called a ditch in the ground
22. a type of boundary where the plates slide sideways past each other
23. caused by the sudden movement from Earth’s crust that results in waves of shaking
