  3. 7. The amount of vibrations in a wave per second.
  4. 10. Huge chunks of Earth crust that explain how the continents actually move.
  5. 14. Scale used to measure earthquake intensity.
  6. 18. A convergent tectonic boundary where one layer goes under the other (makes volcanos).
  7. 19. Second most common element in the atmosphere.
  8. 20. Deformation that bends but bounces back.
  9. 24. Layer of the atmosphere with aurora.
  10. 26. The second waves in an earthquake, they are transverse.

Down
  1. 1. The idea that the continents are "floating" and moving around.
  2. 3. Deformation that bends and stays bent.
  3. 4. The north pole that compasses point at.
  4. 5. Waves that vibrate the same direction they move.
