Document Summary

Seismic refraction: the bending of wave rays as their velocity changes. P waves could go through all mediums, but s waves only go through solids, mainly the liquid outer core combined with the fact they don"t go through the liquid. The p-wave shadow zone were cause by refraction or the core. No s-waves recorded in the interior of the earth because something opaque to the liquid, mainly in the liquid outer core. Something opaque to shear waves due to liquid. The plot of the velocity, the slope of the line. The change in the slope would be cause by the passing from the crust to the lithosphere. The diagram above shows seismic wave arrival times at 6 seismometers. Seismic waves that were recorded at seismometers 1, 2, 3, and 4 have a low velocity than those recorded at seismometers 5 and 6.
