Across
- 2. 2 plates sliding pass each other
- 4. 3rd layer of Earth doing down
- 10. movement of continents across Earth's surface
- 12. thinnest layer of Earth
- 13. proposed continental drift theory in 1900s
- 15. 2 plates moving towards each other
- 16. hot fluid within or below Earth's crust
- 17. found mostly in the core
- 18. occurs when denser plate is pushed under less dense plate
- 20. formed at divergent boundaries
- 22. 2nd layer of Earth doing down
Down
- 1. consists of the crust and upper mantle
- 3. process where magma rises to surface and solidify
- 5. deepest part of Earth's layers
- 6. theory of tectonics plate movement and shape changes
- 7. formed from movement and slips of boundaries
- 8. name of single landmass 245 million years ago
- 9. formed at continental-continental boundaries
- 11. formed at ocean-ocean boundaries
- 14. name of many volcanoes surrounding the Pacific plate
- 19. 2 plates going in different directions
- 21. formed at continental-ocean boundaries
