Plate Tectonics
Across
- 2. earth processes that may lead to widespread damage or risk
- 5. boundary where plates slide past each other
- 7. instrument that measures and records details of earthquakes
- 9. destructive mud flow on the slopes of a volcano
- 11. great mass of falling snow and ice
- 13. a crack in the earths crust
- 15. wave caused by an earthquake
- 17. 2nd wave, s shape, only travel through solids
- 18. the point on earths surface directly above the focus
- 19. the shaking that results from the movement of rock beneath earths surface
Down
- 1. measure of the energy released during an earthquake
- 3. record of an earthquake’s seismic waves produced by a seismograph
- 4. 1st wave, push pull motion, move through solids liquids, and gases
- 6. boundary where two plates move toward each other
- 8. molten rock beneath the earths surface
- 10. magma that reaches earths surface
- 12. the sudden movement of rock and soil down a slope
- 14. boundary where two plates move away from each other
- 16. the point where an earthquake begins
- 17. seismic waves that travel along the ground surface
