Plate Tectonics
Across
- 2. the rising of regions to higher elevations
- 3. upward arching folds
- 4. stress that occurs when forces stratch an object
- 5. the strong lower part of the mantle between the asthenosphere and the outer core
- 7. the surface along which rocks break and slide past each other
- 8. the outermost thin layer of the Earth above the mantle
- 10. the solid outer layer that consists of the crust and upper rigid mantle
- 14. stress that occurs when forces squeeze an object
- 17. a system of satellites used to measure plate tectonic movement
- 18. the central part of Earth
Down
- 1. the layer of rock between the Earth's crust and core
- 3. the soft layer of the mantle on which tectonic plates move
- 5. rock layers folded so that rock layers are horizontal
- 6. a huge body of water that existed along with Pangaea
- 9. the proces in which rock changes shape through states
- 11. the sinking of regions of Earth's crust to lower elevations
- 12. when crust slowly springs back to its original position
- 13. the bending of rock layers due to stress
- 15. a supercontinent that existed 245 million years ago
- 16. downward troughlike folds
