A seismograph station is located 2000 km from an earthquakes epicenter Explain the order that the S and P waves will arrive at the station?

The P waves vibrate very quickly out from the epicenter first in all directions, in a circular way passing the station.

The S waves then vibrate out from the epicenter a few seconds later and cause the sideways shaking of the land as they pass the station.

The P wave then reflects off the core of the Earth and bounces back past the station, followed by the S wave a few seconds later because both waves reflect off the earths core back to the epicenter.
