Which type of fault occurs when the hanging wall moves downward relative to the footwall?

• Reverse fault

• Normal fault

• Strike-slip fault

• Oblique fault

Strike-slip faults cause horizontal movement.

• Agree

Reverse faults are caused by tensional forces.

• Agree

• Disagree

• Shearing

• Compressional

• Rotational

Do all types of faults cause earthquakes?

• Yes

• No

Which two statements about seismic waves are correct?

• P-waves travel faster than S-waves.

• Surface waves are slower but more destructive.

• S-waves can travel through both liquids and solids.

• Body waves cause more surface damage than surface waves.

(a)   waves are the fastest seismic waves and are the first to be detected by seismographs.

S-waves can travel through the Earth's liquid outer core.

• True

• False

A seismograph records P-waves arriving at 2:00 PM and S-waves at 2:05 PM. What does this tell us about the distance of the earthquake's epicenter?

• It is very near the station.

• It is moderately far from the station.

• It is very far from the station.

• It cannot be determined.
