Plate Tectonics
Across
- 1. The outer part of the earth.
- 7. Upper layer of the earths mantle, below the lithosphere.
- 8. The solid, outermost layer of the earth, lying above the mantle.
- 10. Liquid mix of elements, mostly iron and metal.
- 11. drift Gradual movement of the continents.
- 12. A large scale that processes affecting the earths crust.
- 13. The asthenosphere is also__________________.
- 14. Made up of iron and nickle.
- 15. Usually caused when rock underground suddenly breaks along a fault.
- 16. A large chunk of crust.
- 18. crust The relatively thin part of the earth's crust which underlies the ocean basins.
- 19. boundaries Where plates slide past each other.
Down
- 2. This acts like a hard and rigid shell compared to earths mantle.
- 3. The movement of the edge of the plate of the earth's crust.
- 4. Where two plates are moving apart.
- 5. currents A fluid that results from convection.
- 6. A super-continent that moved throughout the years.
- 9. A major fault separating blocks of the earth's surface.
- 11. Where two plates are colliding.
- 17. Mountain or hill that explodes.
