Plate Tectonics
Across
- 2. the type of stress that occurs when an object is squeezed
- 3. The third layer of earth, under the mantle
- 5. When oceanic crust sinks below continental crust
- 6. the theory that the Earth's crust is split up into pieces that move around on top of the mantle
- 7. When two tectonic plates move past each other.
- 9. When two tectonic plates spread apart
- 10. A fault in which the hanging wall moves down relative to the footwall.
- 15. A fault in which the hanging wall moves up relative to the footwall
- 16. the type of stress that occurs when forces act to stretch an object
- 17. The part of the mantle which parts of the lithosphere move.
- 19. The Core of earth, The fourth layer.
- 20. the bending of rock layers due to stress in the Earth's crust
- 21. When two tectonic plates collide.
Down
- 1. The theory that continents can drift apart from one another and have in the past.
- 4. The top layer of earth, where we live.
- 8. The outermost, layer of the Earth that has the crust and also the upper part of the mantle.
- 11. A break in the Earth's crust along which two blocks of the crust slide.
- 12. The amount of force/pressure put on a certain material.
- 13. The lower part of the mantle between the asthenosphere and the outer core.
- 14. When two fault pieces move past eachother.
- 18. The second layer of earth, under the crust
