Earthquakes Review

When scientists map the location of earthquakes, where do they find that most earthquakes happen?

• middle of tectonic plates

• in the core of the earth

• only near mountains

• at plate boundaries

Which scale measures the magnitude, or size, of an earthquake?

• Mercalli

• Richter

• weight

• density

What is the measure of the amount of ground shaking during an earthquake?

• Intensity

• Epicenter

• Magnitude

• Seismogram

Which seismic wave travels the fastest, always being the first detected by seismic stations?

• P waves

• S waves

• Surface waves

• Tsunami waves

The most destructive type of wave is a 

• P-wave
• S-wave
• Surface wave
• transverse wave

How does the Richter Magnitude Scale calculate its measurements?

• Eyewitnesses

• Amount of damage caused

• The amount of time the earthquake lasted

• The strength of the seismic waves recorded by a seismograph machine.

What does a seismograph measure?

• The amount of oil and gas underground.

• The amount of damage an earthquake causes.

• The temperature of the earth's core.

• The amount of shaking of the crust.

How does triangulation show the location of the epicenter of an earthquake?

• By scientist looking around to see where the most damage was created.

• By making triangles on a map.

• By calculating the difference between the P and S waves in arrival times and determining the distances from at least 3 seismic stations.

• By drawing 3 or more random sized circles on a map to see where they intersect.

What is directly above the focus?  

• Epicenter
• Fault
• Seismograph Station
