Waves I Study Guide Vocabulary (Use Your Notes to Do This)
Across
- 3. the height or depth of a wave relative to equilibrium
- 6. the thing s waves cannot travel through.
- 7. compositional earth layer between crust and core
- 8. innermost compositional layer
- 11. the type of interference where two waves overlap to make a smaller wave
- 18. the ability to do work
- 20. the direction transverse waves vibrate particles relative to the direction of energy flow
- 21. outermost mechanical layer of the earth. Crust and top layer of mantle. Brittle.
- 25. one crest and one trough of a transverse wave or one compression and one stretch of a longitudinal wave
- 26. molten layer of iron and possibly nickel.
- 27. the time it takes for one wave cycle to occur
- 28. slower seismic wave transverse
- 30. the number of particles in a given volume
- 33. mechanical layer of earth below lithosphere. Fluid over geologic time scales.
- 34. the length of a cycle, typically measured beteen adjacent crests
- 35. outermostlayer of the earth by composition
- 37. any disturbance that transmits energy
- 38. solid ball of iron and possibly nickel.
- 39. an example of a reflection. What bats do to find food.
- 41. the bending of a wave when it passes around an obstacle or through an opening
- 42. fastest seismic wave longitudinal
Down
- 1. when the crests of one wave overlap the troughs of another wave
- 2. sudden jump in seismic wave speed that indicates a changing layer inside the earth.
- 4. the direction longitudinal waves vibrate particles relative to the direction of energy flow
- 5. fancy term for vibrate
- 9. the bending of a wave when it changes speed as it moves between two different mediums
- 10. any repeated back and forth or up and down motion
- 12. a gas liquid or solid that a mechanical wave travels through
- 13. zone an area where no sesimic waves can be seen. Indicates waves have diffracted or been blocked
- 14. the change in frequency of a wave when the wave source moves towards or away from an observer. Think Ambulance moving to you or away.
- 15. when the crests of one wave overlap the crests of another wave
- 16. mechanical layer of earth between asthenosphere and outer core. Dense and Hard
- 17. discontinuity that identifies the crust and mantle of the earth
- 19. how a wave moves through a substance
- 22. the mixing of two or more overlapping waves.
- 23. a point of no energy. Think calm ocean.
- 24. the discontinuity that identifies the inner core-outer core boundary
- 29. the type of interference where two waves overlap to make a bigger wave
- 31. when a wave bounces off a boundary
- 32. the discontinuity that identifies the outer core-mantle boundary
- 36. the number of cycles per second
- 40. the unit of frequency. Equal to 1/second.
