Plate Tectonics
Across
- 2. a synclinal fold
- 5. the layer of the atmosphere between the stratosphere and the thermosphere and in which temperature decreases as altitude increases
- 7. a monoclinal structure or fold
- 8. the thin and solid outermost layer of Earth above the mantle
- 9. the supercontinent that formed 300 million years ago and that began to break up 250 million years ago
- 11. the boundary between tectonic plates that are colliding
- 14. the boundary between two tectonic plates that are moving away from each other
- 16. the soft layer of the mantle on which the tectonic plates move
- 17. the central part of Earth below the mantle
- 18. rising of regions of the Earth's crust to higher elevations
Down
- 1. the boundary between tectonic plates that are sliding past each other horizontally
- 3. the central part of Earth below the mantle
- 4. the layer of rock between the Earth's crust and core
- 6. stress that occurs when forces act to stretch an object
- 9. the theory that explains how large pieces of Earth's outermost layer, called tectonic plates, move and change shape
- 10. stress that occurs when forces act to squeeze an object
- 12. a block of lithosphere that consists of the crust and the rigid, outermost part of the mantle
- 13. the bending of rock layers due to stress
- 15. an anticlinal rock structure
- 19. a break in a body of rock along which one block slides relative to another
