The numerical rating system that measures the energy, or magnitude, of the largest seismic waves produced by an earthquake is known as the:

• Richter scale

• Mercalli intensity scale

• Moment magnitude scale

• Seismic scale

How much more ground motion would be expected from a magnitude 6 earthquake than a magnitude 3?

• 10 times more

• 100 times more

• 1000 times more

• No difference

The point on Earth's surface directly above where the energy from an earthquake is first released is called the _________________.

• epicenter.

• hypocenter.

• seismic zone.

• fault line.

A __________________________ is a large ocean wave generated by vertical motion of the seafloor during an earthquake.

• tsunami

• hurricane

• tornado

• cyclone

What is true about earthquake prediction?

• Scientists can tell you how likely it is that your area will experience an earthquake, and exactly when the earthquake will occur.

• Scientists can tell you how likely it is that your area will experience an earthquake, but cannot tell you exactly when the earthquake will occur.

• Scientists cannot tell you how likely it is that your area will experience an earthquake, or exactly when the earthquake will occur.

Some areas are more likely to have earthquakes than others because:

• they are located near tectonic plate boundaries.

• they have a lot of tall buildings.

• they are far from the ocean.

• they have a high population density.
