Which of the following is the point on the earth's surface directly above the source of the earthquake?

• Fault plane

• Fault

• Hypocenter

• 4

P waves are faster and more destructive than S waves.

• True

• False

As the distance from the epicenter increases, the magnitude of an earthquake decreases.

• True

• False

The more viscous volcanic materials are, the less effusive an eruption is.

• True

• False

Materials composed of solid, crystalline rocks are more susceptible to mass wasting than do materials composed of mudstones and conglomerate.

• True

• False

Mass wasting happens when shear force overcomes shear strength.

• True

• False
