  16. 40. used to determine the distance of the epicenter from each station
Down
  1. 1. layer of the Earth that consists of crust and upper mantle
  2. 3. seismic wave that travels through the Earth rather than across its surface.
  3. 4. type of boundary that moves away from each other
  4. 6. crust under continents and other land masses
  5. 7. type of convergence where continental and oceanic plates collide
  6. 9. underwater mountain range that is formed by plate tectonics
  7. 10. is the molten or semi-molten natural material from which all igneous rocks are formed
  8. 11. a concentration of heat in the mantle capable of creating magma
  9. 12. states that the Eartgh's surface or the lithosphere is divided into plates that constantly move
