- 18. locations on earth that do not belong to the plate boundary, but seems to have continental volcanic or geothermic activity
- 19. the current most recent supercontinent (all continents joined together)
Down
- 1. the deepest and hottest (under extreme pressure) layer of the earth
- 2. mountain ridges surrounding the ocean ocean floor
- 5. waves that can be transmitted, refracted, and reflected
- 6. occurs when continental crust floats over the oceanic crust
- 8. the only liquid layer of the earth
- 9. occurs when plates slide past each other
- 11. long, slimy depressions appeared in the ocean floor
- 13. when Earth's lithospheric plates moves over the asthenosphere
