Plate Tetonics

2. the original super continent
5. Soft layer of the mantle
7. the theory that the continents have drifted away from each other
9. Outermost, rigid layer of the Earth
10. when 2 plates diverge from each other
11. when an oceanic plate slides under a continental plate
12. formed when 2 continental plates diverge
14. when 2 continental plates slide horizontally past each other
17. plates situated throughout the lithosphere
18. The longest mid ocean ridge on the planet
19. Line of volcanic islands formed by plates colliding and one plate sliding under the other

1. Usually near tectonic plates a tremor in the Earths surface
3. when 2 continental plates collide with each other
4. A deep valley along the ocean floor
6. when 2 plates collide with each other
8. Came up with the theory of Continental Drift
11. the process in which 2 plates are diverging forming new crust along the Mid Atlantic ridge
13. fractures in the earths crust
15. Molten rock
16. when oceanic plates diverge and magma rises through the crust and forms new crust
