- 1. Multiple ChoiceSeismic station A is 5000 kilometers from the epicenter. What is the difference between the arrival time of the first P-wave and the arrival time of the first S-wave recorded at this station?2 minutes 20 seconds6 minutes 40 seconds8 minutes 20 seconds15 minutes 00 second
- 2. Multiple ChoiceWhich process prevented P-waves from arriving at seismic station B?refractionreflectionconvectionconduction
- 3. Multiple ChoiceOnly P-waves were recorded at seismic station C because P-waves travelonly through Earth’s interior, and S-waves travel only on Earth’s surfacefast enough to penetrate the core, and S-waves travel too slowlythrough iron and nickel, while S-waves cannotthrough liquids, while S-waves cannot

- 17. Multiple ChoiceA seismic station located 4,400 kilometers from the epicenter recorded the P-wave and S-wave arrival times for this earthquake. What was the difference in the arrival time of the first P-wave and the first S-wave?4 min 40 sec7 min 35 sec6 min 05 sec13 min 35 sec
