The video mentioned that there are two types of seismic waves that occur in the ground during an earthquake, primary (P waves) and secondary (s waves). What important differences are there between P waves and S waves?

P waves are longitudinal, whereas S waves are transverse.

P waves can travel through solids and liquids, whereas S waves can only travel through solids (this is why it can't travel through the core and the waves refract).

P waves travel faster than S waves.
