Earthquake exam review!

What is a primary earthquake wave that travels through the body of the earth; so named because it is the first wave to reach a seismograph station during an earthquake.

• P-wave

• S-wave

• Surface wave

• body wave

What is the point on the surface of the earth directly above the focus of an earthquake?

• epicenter

• fault

• focus

• intensity

What is the location where the rupture of an earthquake begins and energy is released called?

• epicenter

• focus

• intensity

• S wave

Two types of surface waves

• Love waves and Rayleigh Waves

• P waves and S waves

Which letter represents the movement created by the P Wave?  

• A
• B
• C

Which city is closest to the epicenter?  

• A
• B
• C

What is the zig-zag record made by a seismograph called?

• A. Seismograph

• B. Seismologist

• C. Seismic wave

• D. Seismogram

How do geologists locate the epicenter of an earthquake?

• They measure the difference between seismic waves on three or more seismographs. The epicenter is where the circles intercept.
• They measure the difference between seismic waves on the first seismograph to receive the wave.
• They measure the largest surface wave to hit the surface.
• They add the total damage of the p wave, s wave and surface wave.

Based on the figure, the difference in arrival times between which pair of waves can be used to determine the distance of the recording station to the epicenter?

• C and D

• B and C

• A and D

• A and B

Which of the following seismic waves can travel through gases, liquids, and solids?

• P-wave

• S-wave

• both

• none
