Plate Tectonics
Across
- 1. a theory that proves Alfred Wegners theory of continental drift. Made by Harry Hess
- 3. a theory made by Alfred Wegner
- 7. the earths crust is split into different parts of these
- 11. The way the earth is set up
- 13. squeezing stuff
- 14. the innermost part in the earths composition and is solid due to immense
- 15. Strong lower part of mantle
- 16. the biggest part in the earths composition
- 17. coming together and folding makes mountains and volcanos
- 19. a boundary meaning moving apart
Down
- 2. the outer part of the core
- 4. it is all San Andreas Fault! A crack in the crust when a transform boundary takes place.
- 5. a boundary where the heavier oceanic crust sinks under the lighter continental crust
- 6. plates move side by side
- 8. the innermost part of earth
- 9. this mechanical properity includes the crust and upper mantle
- 10. the earth is split into this way(lithosphere asthenosphere mesosphere core)
- 12. a theory making fact that the tectonic plates are moving everyday
- 14. The outer layer that we live on
- 18. soft plastic like layer in the mechanical map of earth
