Across
- 4. a type of seismic body wave that causes a shearing or side-to-side motion perpendicular to the direction it is traveling
- 7. a wave in which the particles of the medium vibrate parallel to the direction of the wave's energy transfer
- 8. the fastest seismic waves and are the first to be detected during an earthquake
Down
- 1. a geoscientist who studies earthquakes and seismic waves to understand the Earth's internal structure and predict seismic activity
- 2. an elastic wave in the earth produced by an earthquake or other means.
- 3. a disturbance that transfers energy through oscillations that are perpendicular to the direction of the wave's travel
- 5. a tool used to measure the qualities of seismic waves
- 6. a sudden and violent shaking of the ground, sometimes causing great destruction, as a result of movements within the earth's crust or volcanic action.
