[tg.05]which of these statements best explains why p waves arrive earlier than s waves at the seismic station? s waves are generated after p waves arrive at the surface. s waves make longer lines on the seismogram than p waves. p waves are created first and s waves originate from p waves when they are reflected by solid rocks. p waves move straight through all medium and s waves move only through solids in a curvy motion.

P waves move straight through all medium and S waves move only through solids in a curvy motion.

Explanation:

P waves are compression waves, this means that they can travel through all mediums, and all cores of earth, including the inner core, while S waves can only travel through solids, this makes them much more slower. P waves for example can be trackable on the other side of the earth from where the earthquake´s epicenter is, because they travel through the core of the earth, while S waves are only detectable near the epicenter of the earthquake.
