| Question | Answer |
|---|---|
| surface along which rocks move when they pass their elastic limit | Fault |
| vibrations produced when rocks break along fault | Earthquakes |
| rock above the fault surface moves down relative to the rock below the fault surface | normal fault |
| Break in rock caused by compressive forces where rock above the fault surface moves upward relative to the rock below the fault surface | Reverse Fault |
| rocks move past eachother without much vertical movement | stike-slip fault |
| a large section of earth's crust and rigid upper mantle that moves around on the athenosphere | Plate |
| wave generated by an earthquake | seismicwave |
| seirmic wave that moves rock particles back and forth in the same direction that the wave travels. | primary wave |
| seismic wave that moves rock particles atright angles to the direction of the wave | secondary wave |
| seismic wave that moves particle up and down in a backward rolling motion and side to side in a swaying motion | surface wave |
| point on earth's surface directly above an earthquake focus | epicenter |
| instrument used to register earthquake waves and record the time that each arrived | seismograph |
| rhythmic movement that carries energy through matter and space | wave |
| the highest point of a earthquake | crest |
| measure of the energy released during an earthquake | magnitude |
| in an earthquake the point below earth's surface where energy is released in the form of seismic waves | focus |
| occurs when wet soil acts more like a liquid during an earthquake | liquetaction |
| seismic sea wave that begins over an earthquake focus and can be highly destructive when it crashes on shore | hunami |
