Most of what we know about the interior of the earths comes from the study of seismic waves from earthquakes. primary waves are compressional waves that are longitudinal in nature while secondary waves are shear waves that are transverse waves. notice how the change in the velocity of s-waves to 0km/s what does it tell us about the nature of earths interior
