  1. 2. A longitudinal wave is a wave where particles in the medium vibrate parallel to the direction of wave travel, creating regions of compression (particles close together) and rarefaction (particles spread apart).
  2. 3. A seismologist is a scientist who studies earthquakes and seismic waves, using data from instruments like seismographs to understand Earth's interior, forecast natural disasters, and locate resources like oil and gas.
  3. 5. 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.
  4. 7. Vibrations that travel through Earth carrying the energy released during an earthquake
  5. 8. a type of seismic wave that shakes the ground from side to side or up and down, perpendicular to the direction it's traveling.

  1. 1. a wave vibrating at right angles to the direction of its propagation.
  2. 4. a type of seismic wave that shakes the ground from side to side or up and down, perpendicular to the direction it's traveling.
  3. 6. An instrument used to determine an earthquake’s strength and location
