Plate Tetonics

2. when oceanic plates diverge and magma rises through the crust and forms new crust
5. A deep valley along the ocean floor
8. the theory that the continents have drifted away from each other
9. the original super continent
13. the process in which 2 plates are diverging forming new crust along the Mid Atlantic ridge
14. plates situated throughout the lithosphere
16. Molten rock
17. when 2 continental plates slide horizontally past each other
18. Soft layer of the mantle
19. when 2 continental plates collide with each other

1. Outermost, rigid layer of the Earth
2. The longest mid ocean ridge on the planet
3. Usually near tectonic plates a tremor in the Earths surface
4. when 2 plates collide with each other
6. Came up with the theory of Continental Drift
7. fractures in the earths crust
10. formed when 2 continental plates diverge
11. Line of volcanic islands formed by plates colliding and one plate sliding under the other
12. when 2 plates diverge from each other
15. when an oceanic plate slides under a continental plate
