Across
- 3. Name of the layer of the Earth where the solid crust and uppermost mantle are found
- 4. Type of plate that is underneath the ocean
- 7. Type of boundary movement where two plates slide past one another
- 10. Ocean-based disaster caused by an earthquake at sea
- 11. Type of plate that is carrying land (a continent)
- 13. The layer named after being "weak" because it is somewhat liquid, allowing the tectonic plates to float on top of them
- 15. An opening or large offset created by the separation of plates
- 16. Outermost solid layer of the Earth, home of the tectonic plates
- 17. Layer of the Earth beneath the crust but outside of the core. Mainly liquid rock.
- 19. Type of boundary movement where two plates move toward each other
- 20. A ground-shaking movement due to the movement of tectonic plates
- 21. Name of the proposed supercontinent that existed before today's continents drifted apart
Down
- 1. Name of the process that causes continental drift (happens at the bottom of the sea)
- 2. Geological formation that forms during sea floor spreading
- 5. Liquid rock that rises to the surface of the earth's crust through a volcano
- 6. Name of the region/border shared by two plates
- 8. Where one plate moves on top of another plate
- 9. Type of boundary movement where two plates move away from each other
- 12. Land-based disaster caused by an earthquake affecting the surfaces of hills/mountains
- 14. The point on the ground closest to the origin of an earthquake
- 16. Innermost layer of the Earth, which is made of iron.
- 18. Liquid rock from beneath the crust of the earth
