Across
  1. 2. Creep Displacement along a fault that is so slow and gradual that little seismic activity occurs.
  2. 3. Waves (S waves) Temporarily change the shape of the material that transmits them.
  3. 6. An instrument that records earthquake waves.
  4. 10. The record a seismograph makes.
  5. 12. The study of earthquakes and seismic waves.
  6. 13. The zone within earth where rock displacement produces an earthquake.
  7. 14. Waves (P waves) Consist of a rhythmic push-pull motion- they push (compress) and pull (expand) rocks in the direction of wave travel.
Down
  1. 1. Waves Seismic waves that travel along the outer layer of Earth.
  2. 4. Smaller earthquakes that follow the main earthquake.
  3. 5. Small earthquakes that often that often precede a major earthquake.
  4. 6. waves shake the particles at right angles to their direction of travel. liquids and gasses will not transmit S waves.
  5. 7. The vibration of Earth produced by the rapid release of energy.
  6. 8. band The sudden release of stored strain in rocks that result in movement along a fault.
  7. 9. Waves Seismic Waves that travel through Earth's interior.
  8. 11. The location on the surface directly above the focus.
