Ch 12 Review

An area where no direct seismic waves from a particular earthquake can be detected is called

• an inactive fault zone.

• the mesosphere.

• a shadow zone.

• the atmosphere.

The composition of Earth’s interior affects

• how long an earthquake will last.

• the speed and direction of seismic waves.

• the location of an earthquake’s focus.

• the strength of an earthquake.

Rayleigh waves cause the ground to move

• in a horizontal direction.

• in a back-and-forth direction.

• in a jerky, up-and-down motion.

• in an elliptical, rolling motion.

Which scale more accurately measures the magnitude of large earthquakes?

• modified Mercalli scale

• Richter scale

• moment magnitude scale

• Mohs scale

A modern seismograph consists of

• three sensing devices.

• four sensing devices.

• two sensing devices.

• 10 sensing devices.

To find the distance to an earthquake’s epicenter, scientists

• chart the lag time between preshocks and aftershocks.

• use radio wave detection devices.

• analyze the arrival times of the P waves and S waves.

• analyze the arrival times of the Love waves and Rayleigh waves.

To locate the epicenter of earthquakes, scientists use computers to

• analyze hypotheses and theories.

• perform triangulations based on data from seismograph stations.

• detect vibrations.

• determine magnitude and intensity.

If you are in a car during an earthquake, you should

• drive toward a bridge.

• stop the car in a safe place.

• get out and run.

• park near a tall building.
