Across
- 6. spot a stationary warm area
- 7. plates plates below the continents
- 9. tectonics earth's crust and upper mantle are broken into sections called plates
- 11. mid-oceanic ridges form from these
- 13. how many types of boundaries are there?
- 14. plastic layer below the lithopsphere
- 17. current hot magma moves towards the surface, cools, sinks again
- 19. forms from the friction of transform boundaries
Down
- 1. the earth's crust and upper mantle, earth's outer shell
- 2. ridges under water mountains
- 3. subduction zones happen here
- 4. mountains when 2 continental plates collide creates what?
- 5. zones where less dense plates slide under the more dense plates
- 8. lava erupting from the earth's surface
- 10. 2 plates that slide past each other cause friction, than an earthquake
- 12. 2 oceanic plates colliding
- 15. plates plates below the ocean
- 16. valleys a feature of divergent boundaries
- 18. do hot spots ever move?
