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