Plate Tectonics
Across
- 2. Stresses that cause rocks to shorten
- 3. Boundary where two tectonic plates move horizontally against each other
- 9. Lowland region that forms where Earth's tectonic plates move apart
- 10. Compressed plates that fold upward
- 13. Boundary where two tectonic plates collide together
- 14. Hanging wall has moved upward above the foot wall
- 16. Sudden shaking of the rock in the Earth's crust
- 17. Super continent that incorporated almost all the landmasses on Earth
- 18. Hanging wall and foot wall are even in height but moving horizontally
- 20. Compressed plates that fold downward
Down
- 1. Movements of circulation patterns made by differential heating
- 4. Boundaries where two plates converge, and one plate is thrust beneath the other
- 5. Boundary where two tectonic plates move away from each other
- 6. Stresses that cause rocks to elongate
- 7. Gigantic pieces of the Earth's crust and uppermost mantle
- 8. Wave of acoustic energy that travels through the Earth
- 11. The theory that Earth's land masses are in constant motion
- 12. Hanging wall has moved downward below the foot wall
- 15. Separates the earth into plates
- 19. Stresses that cause rocks to slip past each other
