Plate Tectonics

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

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
