10.1 Earthquakes Quiz

At a _____________ fault, rocks on either side of the fault surface move past each other.

• normal
• reverse
• elastic
• strike-slip

The most destructive seismic waves are ____________.

• primary
• P-waves
• secondary waves
• surface waves

A break in Earth's lithosphere where one block of rock moves toward, away from, or past another is called a ______________.

• fault
• strain
• earthquake
• stress

Which factor does not affect the speed of a seismic wave?

• temperature of the rock

• chemistry of the rock

• season of the year

• pressure

The ______________ waves are the first to reach a seismometer after an earthquake.

• surface
• primary
• secondary
• tsunami

Along a ____________ fault, rock above the fault surface moves upward in relation to rock below the fault surface due to compression forces.

• reverse
• strike-slip
• elastic
• normal

Along a __________ fault, rock above the fault surface moves downward in relation to rock below the fault surface due to diverging tension forces.

• reverse
• strike-slip
• elastic
• normal

A normal fault occurs where forces pull two blocks of rock apart. At which kind of plate boundary does this occur? Why?

• convergent plate boundary- this is where plates are coming closer together
• convergent plate boundary- this is where plates are moving apart
• divergent plate boundary- this is where plates are coming closer together
• divergent plate boundary- this is where plates are moving apart

A person located twice as far from a epicenter of an earthquake as another person will notice that the time between the arrival of the primary and secondary waves will be ____________.

• the same
• reduced
• increased
• unnoticeable

When the force on rocks is great enough, they break, producing vibrations called _____________.

• faults
• strains
• earthquakes
• stresses
