This classroom lecture presents a simple conceptual model of the relative thicknesses of the Lithosphere by measuring a simple hard-boiled egg. The hard-boiled egg is used as a scale model for the zones of the Earth. The shell is to the egg as the lithosphere is to the Earth. This demonstration...

The seismic shadows are the effect of seismic waves striking the core-mantle boundary. P and S waves radiate spherically away from an earthquake's focus in all directions and return to the surface by many paths. S waves, however, don't reappear beyond an angular distance of ~103° (as they are...
