A break in Earth's crust along which movement occurs.

Match the following

• Richter magnitude scale

• measures intensity if an earthquake based on damage done

• moment magnitude scale

• rates the magnitude of the largest seismic waves produced by an earthquake

• Modified Mercalli scale

• rates the total energy released by an earthquake

As you go up one unit on the Richter magnitude scale,

• twice as much ground motion occurs

• ten times as much ground motion occurs

• one hundred times as much ground motion occurs

• one million times as much ground motion occurs

As you go up one unit on the Richter magnitude scale,

• twice as much energy is released

• ten times as much energy is released

• thirty-two times as much energy is released

• 50% more energy is released

The amount of damage caused by an earthquake depends on

• strength of earthquake

• nature of surface materials

• design of structures

• distance to epicenter

The point on Earth's surface directly above the place where the earthquake's energy is released:

Match the following

• landslide

• violent ocean wave caused by an underwater earthquake

• pancaking

• rapid downhill movement of soil, loose rock, and boulders

• liquifaction

• wet soil becomes like a liquid due to shaking of ground

• tsunami

• collapse of a building during an earthquake
