Across
- 3. where convection currents take place
- 6. solid metal core
- 8. low silica low viscosity lava
- 9. compressional wave, faster, moves through solids and liquids
- 11. plates slide across each other
- 13. sinking of one plate under another due to density
- 14. low silica low viscosity
- 16. vent that allows magma to flow from the inside of the earth
- 17. pushing of plates away from each other
- 18. where earthquakes happen on the surface
- 19. where earthquake originates deep underground
- 21. waves used as evidence for the earth's interior
- 23. liquid metal responsible for magnetic field
Down
- 1. movement due to density that moves tectonic plates
- 2. theory that states plates move slowly over time due to convection currents
- 4. plates moving away from each other
- 5. broken into tectonic plates
- 7. strength of earthquakes
- 10. release of sound wave energy due to tension/pressure build up due to movement
- 12. plates moving towards each other
- 14. transverse waves, slower, moves through liquid only
- 15. high viscosity high silica lava
- 20. area where the most active plates are
- 22. pull of lithosphere during subduction
