The slowest-moving waves and are destructive when traveling through loose earth.

Vibrations of the earth’s crust.

A place where the fault is locked an unable to move.

The difference in time between the primary and secondary waves.

Why do earthquakes usually occur at plate boundaries?

An aftershock is

Energy released in the form of vibrations.

What is elastic rebound?

How do scientists find the epicenter of an earthquake?

Vibrations in the earth caused by the sudden movement of rock are called?

At what location does the first motion of an earthquake occur?

The amount of damage caused by an earthquake.

Which of the following rules should be followed before and after an earthquake?

The area along a fault where slippage first occurs.

Through which type(s) of material(s) do P waves travel fastest?

What should you do if you are indoors during an earthquake?

When a fault springs back to its original shape and position.

Earthquakes with magnitudes less than 2.5.

A group of interconnected faults.

Which of the following is most likely to affect how a building responds to seismic waves?

The second waves to be recorded and can travel only through solids.

A device that detects and records seismic waves.

How does the structure of Earth’s interior affect seismic waves?

The point on the earth’s surface directly above the focus.

A series of smaller tremors.

The elastic rebound theory states that as a rock becomes stressed, it first…

Which of the following is NOT a cause of tsunamis?

A major earthquake with an epicenter on the ocean floor that causes a giant ocean wave.

Fault zones form at plate boundaries because

During an earthquake, a building

A scale that compare the energy released by different earthquakes.

The difference between the arrival time of the primary and secondary waves.

A scale that expresses the magnitude of an earthquake.

A scale that express the intensity of an earthquake by Roman numerals.

If you are indoors during an earthquake, you should

Move the fastest and can travel through solids, liquids, and gases.
