- 1. Multiple ChoiceWhat are seismic waves?Energy released by an earthquake in waves or vibrationsThe point beneath Earth’s surface at which rock under stress breaks and triggers an earthquakeThe point on the surface directly above the point at which an earthquake occursThe strength of an earthquake
- 2. Multiple ChoiceIn what order do the three types of seismic waves arrive at a seismograph?S wave, P wave, Surface waveSurface wave, P wave and S waveP wave, S wave and Surface waveP wave, Surface wave and S wave
- 3. Multiple ChoiceWhich type of seismic wave produces the most severe ground movement?P waveS waveSurface waveNone of the above
- 4. Multiple ChoiceDescribe the moment magnitude scale, and explain why it is useful in measuring earthquakes.It measures nearby earthquakes.It measures earthquakes total energy of earthquakes near or farIt tells us how dangerous an earthquake wasIt measures the size of the largest wave.
- 5. Multiple ChoiceHow do geologists locate the epicenter of an earthquake?They measure the difference between seismic waves on three or more seismographs. The epicenter is where the circles intercept.They measure the difference between seismic waves on the first seismograph to receive the wave.They measure the largest surface wave to hit the surface.They add the total damage of the p wave, s wave and surface wave.
- 6. Multiple Choice_____________ records ground movements caused by seismic waves as they
move through EarthFocusEpicenterSurface WavesSeismograph - 7. Multiple Choice________ are the slowest seismic waves.P wavesS wavesSurface wavesEpicenter
- 8. Multiple Choice___________ is the point beneath Earth’s surface at which rock under stress breaks and triggers an earthquake.FocusEpicenterSurface wavesSeismograph
- 9. Multiple Choice__________ is the point on the surface directly above the point at which an earthquake occurs.FocusEpicenterSurface wavesSeismograph
- 10. Multiple ChoiceTrue or False? The shaking and trembling that results from movement of rock beneath Earth’s surface is called an earthquake.TrueFalse, magma
- 11. Multiple ChoiceTrue or False? Earthquakes are caused by the forces of mountain movement.TrueFalse, plate
- 12. Multiple ChoiceTrue or False? The epicenter of an earthquake is below the focus.TrueFalse, above
- 13. Multiple ChoiceTrue or False? P waves can become surface waves when they reach Earth’s
surface.TrueFalse, no waves - 14. Multiple ChoiceTrue or False? The Modified Mercalli scale rates the amount of damage from an earthquake.TrueFalse, energyFalse, shaking
- 15. Multiple ChoiceTrue or False? To locate the epicenter of an earthquake, geologists need data from two or more
seismographs.TrueFalse, three - 16. Multiple ChoiceThe seismic waves that move fastest are _________P wavesS wavesSurface waves
- 17. Multiple ChoiceGeologists use the moment magnitude scale to rate the total ________ released by an earthquake.SizeEnergyShaking
