Across
- 1. an example of a convergent boundary
- 4. convection currents move through it to power tectonic plates
- 6. top layer of the tectonic plates it has a high density and results from the cooling of magma
- 11. earths largest plate and formed a part of a series of islands near North America
- 13. transform boundaries cause when energy is released
- 14. it is a plate that covers the entirety of a country, and it also covers a part of Asia
- 16. lies above the fault plane
- 18. Earth's lithosphere is recycled into earths mantle at convergent boundaries
- 19. break in earth's crust
- 20. are mostly found underwater
- 21. the rigid outer part of the earth
Down
- 2. can be between continental plates
- 3. occurs at mid-ocean ridges,new oceanic crust is formed
- 5. is the most important source of magma and is directly below the lithosphere
- 7. it is a layer of rock that forms below the continents, and has a low density
- 8. form deep trenches
- 9. Earth's thin outer shell of rock
- 10. drive the movement of tectonic plates
- 12. two tectonic plates collide to form
- 15. the theory that earth's continents moved over time, but they were on tectonic plates so they slowly moved away
- 17. ocean to continent example of a transform boundary
