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