Across
- 2. Plates colliding with each other.
- 3. Seismic wave that travels along Earth's surface.
- 6. Place where extremely hot material from inside Earth erupts at the surface.
- 7. One plate sinks below another plate.
- 8. Huge wave in the ocean caused by earthquakes or other disruptions.
- 11. Separating of continents by drifting across Earth's surface.
- 14. Molten rock that has erupted onto Earth's surface.
- 15. Longitudinal seismic wave that travels fast through Earth.
- 16. Point on Earth's surface directly above the focus of an Earthquake.
- 18. Place below the ground where earthquake starts.
- 19. Plates move apart from each other in opposite directions.
- 21. Crust that forms continents.
- 22. Molten rock below Earth's surface.

Down
- 1. Section of crust that moves about on the Earth's surface.
- 3. New crust forms at ocean ridges and spreads outwards.
- 4. Formed by crust crumpling upwards as plates collide.
- 5. Isolated place away from plate boundaries where a lot of hot magma is collecting.
- 9. Transverse seismic wave that travels through Earth.
- 10. Rapid movement of the ground due to movement of tectonic plates.
- 12. Deep channel in ocean floor where crust is sinking downwards.
- 13. Plates sliding past each other in opposite directions.
- 17. The centre of Earth.
- 20. Zone where Earth's crust and mantle are being pulled apart.
