Plate Tectonics
Across
- 2. Longitudinal waves that travel fast.
- 3. Oceanic plate sinks below the continental plate.
- 5. Waves Slowes waves that cause the most destruction.
- 9. An opening in the surface of the Earth through which magma erupts.
- 10. Boundaries Two plates move- away from each other.
- 11. The thin outer layer of the Earth's surface
- 12. Shaking of the Earth caused by a sudden movement of rock beneath its surface.
- 15. Boundaries Two plates slide past each other.
- 18. wave The shaking of the ground in an earthquake.
- 19. Crust Crust that forms the ocean floor.
Down
- 1. Stripping Magnetism trapped in rocks on each side of plate boundaries.
- 3. It detects seismic waves from an earthquake
- 4. Sea waves caused by earthquakes.
- 6. Boundaries Plates collide with each other.
- 7. The innermost layers of the Earth.
- 8. Currents Movement of heat through a liquid.
- 13. Molten rock.
- 14. Theory Continental Drift
- 16. Waves Transverse waves that are slower than P-waves.
- 17. The layer of rock that lies between the crust and the outer core of the Earth.
