Across
- 3. measures earthquakes
- 4. this is a type of wave that occurs on the surface
- 8. a facture or break in the earths lithosphere
- 10. a long high sea waves caused by an earthquake
- 11. Scale measure energy released / rock strength / how much movement their was
- 13. the time between where stations pick up the earthquake/ speed seismic waves travel
- 14. a release in this in a fault or built rock causes earthquake
- 15. a way to protect buildings in areas known for earthquakes and tsunamis
- 16. fastest, solid, liquid, gas, known as the "p" wave
- 19. when a Collison between an oceanic and continental plates and the continental plates go under.
- 21. the point on the earth's surface vertically above the focus of an earthquake
Down
- 1. a deep depression of the sea floor caused by subduction of one plate under another
- 2. the act or process of liquefying or making liquid
- 5. this theory gave evidence to support the theory of the continental drift
- 6. 2nd fastest, solid
- 7. older scale to track speed of ground movement
- 9. process using 3 stations to find the focal point
- 12. it the measurement of the strength of the earthquake
- 17. a small earthquake occurring after a larger earthquake, causes more damage sometimes
- 18. a valley shaped area of the earth in which the plates of the crust are moving away from each other forming cracks and faults
- 20. when an oceanic crust melts due to this formation.
