Across
- 2. lava flows
- 7. thought to be responsible for the movements of the plates
- 8. a record sheet (on a drum)
- 9. a plate we live on
- 10. where magma is stored
- 14. plates moving apart , rifting, no folds (normal faults form)
- 17. magma that reaches the surface
- 18. plates are made of this layer of the earth (it is 100km thick)
- 19. shaking of earths crust caused by s release of energy
Down
- 1. a type of wave (goes through only solids and is the slowest)
- 3. a measure of the amount of damage done (measured on mercalli scale)
- 4. lava blows
- 5. a way of diving the earth
- 6. formed from subduction zone between Juan de Fuchs plate and North American plate (ie Mount St. Helens)
- 10. molten rock underground
- 11. boiling hot springs (erupts violently)
- 12. measures magnitudes (ground motion goes up by x10 energy release by x30
- 13. the point on earths surface directly above the focus
- 15. division between crust and mantle
- 16. fissures in the ground (steam and hot gases form)
