Read each question carefully and answer to the best of your ability. For multiple-choice questions, select the best option. For short answer questions, provide concise and accurate responses.
1. Which type of seismic wave arrives first at a seismograph station?
S-waves
P-waves
Surface waves
Love waves
2. What is the minimum number of seismograph stations required to locate an earthquake's epicenter?
One
Two
Three
Four
3. The point on the Earth's surface directly above the focus of an earthquake is called the .
4. The difference in arrival times between P-waves and S-waves helps seismologists determine the to the epicenter.
5. Briefly explain how a seismograph works to detect seismic waves.
6. S-waves can travel through both solid and liquid layers of the Earth.
True
False
7. The triangulation method uses data from at least three seismic stations to pinpoint an earthquake's epicenter.
True
False
8. Observe the diagram below, which illustrates different types of seismic waves.

Based on the diagram, describe one key characteristic that differentiates P-waves from S-waves.
