Across
- 1. primary, up and down, first wave
- 3. most seismic and volcanic plate
- 6. Juan de Fuca and North America collide to form this
- 7. cannot travel through the outer core
- 8. transverse, secondary, body waves, most dangerous
- 9. when one plate slides under the other
- 11. crust is neither created or destroyed at this boundary
- 14. ONLY new crust
- 15. sudden movement of rocks
- 17. crust is destroyed
Down
- 1. ocean that is disappearing due to convergent boundaries
- 2. this if formed at divergent boundary
- 4. spot above focus
- 5. measured on Mercalli Scale
- 8. Most active fault in the world
- 10. this boundary creates volcano, volcanic island arc, trench and subduction zone
- 12. The city that is last to receive p-wave
- 13. exact spot of earthquake
- 16. magnitude
