Across
- 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
Down
- 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
