Across
  1. 2. Plates colliding with each other.
  2. 3. Seismic wave that travels along Earth's surface.
  3. 6. Place where extremely hot material from inside Earth erupts at the surface.
  4. 7. One plate sinks below another plate.
  5. 8. Huge wave in the ocean caused by earthquakes or other disruptions.
  6. 11. Separating of continents by drifting across Earth's surface.
  7. 14. Molten rock that has erupted onto Earth's surface.
  8. 15. Longitudinal seismic wave that travels fast through Earth.
  9. 16. Point on Earth's surface directly above the focus of an Earthquake.
  10. 18. Place below the ground where earthquake starts.
  11. 19. Plates move apart from each other in opposite directions.
  12. 21. Crust that forms continents.
  13. 22. Molten rock below Earth's surface.
  14. 23. Layer beneath Earth's crust.
Down
  1. 1. Section of crust that moves about on the Earth's surface.
  2. 3. New crust forms at ocean ridges and spreads outwards.
  3. 4. Formed by crust crumpling upwards as plates collide.
  4. 5. Isolated place away from plate boundaries where a lot of hot magma is collecting.
  5. 9. Transverse seismic wave that travels through Earth.
  6. 10. Rapid movement of the ground due to movement of tectonic plates.
  7. 12. Deep channel in ocean floor where crust is sinking downwards.
  8. 13. Plates sliding past each other in opposite directions.
  9. 17. The centre of Earth.
  10. 20. Zone where Earth's crust and mantle are being pulled apart.
