  6. 18. the ability to do work
  7. 20. the direction transverse waves vibrate particles relative to the direction of energy flow
  8. 21. outermost mechanical layer of the earth. Crust and top layer of mantle. Brittle.
  9. 25. one crest and one trough of a transverse wave or one compression and one stretch of a longitudinal wave
  10. 26. molten layer of iron and possibly nickel.
  11. 27. the time it takes for one wave cycle to occur
  12. 28. slower seismic wave transverse
  13. 30. the number of particles in a given volume
  14. 33. mechanical layer of earth below lithosphere. Fluid over geologic time scales.

Down
  1. 1. when the crests of one wave overlap the troughs of another wave
  2. 2. sudden jump in seismic wave speed that indicates a changing layer inside the earth.
  3. 4. the direction longitudinal waves vibrate particles relative to the direction of energy flow
