Plate Tectonics
Across
- 3. A fault in which the hanging wall moves down relative to the footwall.
- 8. The outermost, ridged layer of the Earth that consists of the crust and the ridged upper part of the mantle.
- 10. The layer of the Earth between the crust and the core.
- 12. The process by which new oceanic lithosphere is created at mid-ocean ridges as older material is pulled away from the ridge
- 14. "Middle Sphere" the strong, lower part of the mantle between the asthenosphere and the outer core.
- 15. The region where an oceanic plate sinks down into the asthenosphere at a convergent boundary.
- 17. A fault in which the hanging wall moves up relative to the footwall.
- 18. The amount of force per unit area that is put on a given material
- 19. The liquid layer of the Earth's core that lies beneath the mantle and surrounds the inner core.
- 20. The bending of rock layers due to stress in the Earth's crust.
Down
- 1. The thin, outermost layer of the Earth, or the uppermost part of the Lithosphere.
- 2. The theory that continents can drift apart from one another and have done so in the past.
- 4. The soft layer of the mantle on which pieces of the lithosphere move.
- 5. The central spherical part of the Earth below the mantle.
- 6. A fault in which the two fault blocks move past each other horizontally.
- 7. The solid, dense center of the Earth.
- 9. A break in the Earth's crust along which two blocks of the crust slide relative to one another.
- 11. The type of stress that occurs when forces act to stretch an object.
- 13. A piece of the lithosphere that moves around on top of the asthenosphere.
- 16. The type of stress that occurs when an object is squeezed.
