How Do Earthquakes Allow Us to Model the Structure of Earth's

Question

Examlex · Accepted Answer

The Answer is Examining the different seismic waves, we find P and S waves are not recorded allover the planet. There is a blind spot for S waves on the side of Earth opposite the earthquake,and there is a shadow zone partway around the surface from the earthquake. Since we know Swaves cannot travel through liquid and P waves can, we conclude the Earth's core is liquid. SinceP waves bend when they enter the liquid core, but some travel straight through, it implies there isa solid center to the liquid outer core.
