The diameter of Earth's core and the nature of the outer core were discovered by analyzing the P-wave and S-wave shadow zones. P-waves can pass through solids and liquids, but S-waves can only pass through solids. By analyzing the pattern of P-waves and S-waves that are detected after an earthquake, scientists were able to deduce that there must be a liquid outer core and a solid inner core, as S-waves cannot pass through the liquid outer core. The depth and size of the core were also estimated based on the extent of the shadow zones.
