Plate Tectonics
Across
- 2. the middle layer of the earth.
- 3. The mechanical model; lithosphere, asthenosphere, mesosphere, outer core, inner core. (look at me on ice)
- 5. a boundary where the plates move away from eachother
- 6. the outer layer of the core.
- 9. a divergent boundary where new crust is formed in the ocean
- 12. the theory that the continents are always moving.
- 14. the cracked-up parts of earths crust.
- 15. when something is pressed together.
- 16. the center of the earth.
- 17. the 3rd mechanical layer
- 18. the 1st mechanical layer
Down
- 1. the theory of plates moving on the asthenosphere
- 4. when the plates slide past eachother
- 7. what something is composed of.
- 8. when the plates come together.
- 9. when one plate (usually the denser, oceanic plate) go under another.
- 10. A long rigid crack in the earths surface.
- 11. the inner layer of earths center
- 12. the very outer layer of the earth.
- 13. the 2nd mechanical layer
