Plate Tectonics
Across
- 1. the center of the earth
- 5. the only habitable planet
- 6. Appears when continental plates collide
- 8. the rock material which lies below the fault plane
- 12. a fracture between two blocks of rock
- 13. A process moving around rocks and minerals below earth's surface
- 15. when two sides of a fault slide into each other
- 16. the bottom of the sea
- 17. A long narrow ditch
- 18. slabs of oceanic lithosphere descend into the mantle
Down
- 1. when two plate move towards each other
- 2. A mountain or hill that erupts
- 3. the mostly solid bulk of the earth's interior
- 4. a very very large mass of land
- 7. moltin rock and earths crust
- 9. when two plates move away from each other
- 10. Alfred Wegner came up with this theory
- 11. when plates slide past each other
- 13. the outer layer of the earth
- 14. a person who studies rocks and earth's landforms
