Plate Tectonics

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.

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.
