a large section of earths crust and rigid upper mantle that moves around on the asthenosphere | plate |
surface along which rocks move when they passs their elastic limit and break | fault |
vibrations produced when rocks break along a fualt | earthquake |
break ion rock caused by tension forces, where 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 surfaces move upward rocks relative to the rock bleow the fault surface | reverse fault |
break in rock caused by shear forces, where rocks move past each other without much vertical movement | strike-slip fault |

seismic wave that moves rocks particles at rigth angles to the direction of the wave | secondary wave |
seismic waves that moves rock particles up-and-down in backward rolling motion and side-to-side ina swaying motion | surface wave |
point on Earths surface directly above an earthquakes focus | epicenter |
instrument used to register earthquake waves and record the time that each arrived | seismograph |
