Across
- 2. the thickest part of the earth, and is under the crust
- 5. when two tectonic plates separate
- 6. the theory that explains how large peices of the Earth's crust move and change shape
- 8. the outermost part of the core
- 10. a big crack in the earth, due to a transform boundary
- 12. stress that occurs when the forces act to squeeze an object
- 14. upper mantle
- 16. the ring of fire is a good example of this
- 17. the part of the earth we live on
- 18. how the layers of the earth move and behave
- 19. when two tectonic plates slide past each other, or one slides past another
Down
- 1. gigantic pieces of the crust and upper mantle, they move due to convection currents and contenental drift
- 3. a theory that Harry Hess discovered, and it is when magma comes out of the earth to make more (bank)
- 4. the theory that the continents are moving
- 7. the center of the earth, it is also under the mantle
- 9. another name for the crust and upper mantle
- 11. another name for lower mantle
- 12. some of these layers are the continental crust, oceanic crust,mantle, and core
- 13. when two tectonic plates come together
- 15. the innermost part of the core, is also solid due to the pressure of all the other layers of the earth
