Base your answer on the diagram below and on your knowledge of Earth science. The diagram represents a cut-away view of Earth's interior and the paths of some of the seismic waves produced by an earthquake that originated below Earth's surface. Points A, B, and C represent seismic stations on Earth's surface. Point D represents a location at the boundary between the core and the mantle.
Seismic 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 and 20 seconds
6 minutes and 40 seconds
8 minutes and 20 seconds
15 minutes and 00 seconds

Distance to epicenter: 3350 km
S-wave travel time: 4 min 50 sec
Distance to epicenter: 3350 km
S-wave travel time: 6 min 10 sec

P-wave arrival time, only
S-wave arrival time, only
difference in the arrival time of the P-wave and S-wave
difference in the height of the P-wave and S-wave
