Plate Tectonics

3. The supercontinent where all land was once together
7. The theory that all of Earth was once together
10. a sudden and violent shaking of the ground, sometimes causing great destruction, as a result of movements within the earth's crust or volcanic action
11. a lowland region that forms where Earth's tectonic plates move apart, or rift.
12. the upper layer of the earth's mantle, below the lithosphere, in which there is relatively low resistance to plastic flow and convection is thought to occur.
15. The crashing/colliding of two plate boundaries
16. Two plates that slide past each other
17. Where two plates slide past each other and cause earthquakes

1. when an oceanic plate runs into a continental plate and slides beneath it.
2. rigid, rocky outer layer of the Earth, consisting of the crust and the solid outermost layer of the upper mantle/where the plates are located
4. Scientist who came up with the Continental Drift Theory
5. Created when two continental plates collide
6. The theory that says HOW the continents move around
8. Created when a Oceanic plate and Continental Plate crash together
9. The separation of two plate boundaries
13. long, narrow depressions on the seafloor that form at the boundary of tectonic plates where one plate is pushed, or subducts, beneath another.
14. a seafloor mountain system formed by plate tectonics
