Plate Tectonics
Across
- 2. a continuous elevated zone on the floor of all the major ocean basins.
- 5. hypothesis that said all present continents nice existed as a single supercontinent
- 6. Process that deforms Earth’s Crust for structural features.
- 7. Primary driving force for movement of tectonic plates
- 8. German Meteorologist and geophysicist
- 13. trench a narrow and elongated depression of the seafloor
- 15. when igneous rocks melt over a temp range.
- 16. The name of the supercontinent including all of the existing continents
- 17. Where two plates move apart.
- 18. a boundary in which two plates more together.
- 19. a hypothesis that said new ocean crust is produced at the crests of mid-ocean ridges.
Down
- 1. a chain of volcanic islands
- 2. Two ocean slabs converge.
- 3. a boundary when two plates slide past one another.
- 4. when two continental plates collide
- 9. Largest plate
- 10. elevated areas of the seafloor characterized by high heat flow and volcanism.
- 11. as tectonic forces continue to pull apart the crust, the fragments sink which causes this.
- 12. linear zones of irregular topography on the deep-ocean floor.
- 14. Theory that says Earths outer shell consists of individual plates.
