WebbThe seismic waves called P-waves pass through the core and are detected on the far side of the Earth. Indirect signals received in the P-wave shadow zone suggest there is a solid inner core deflecting some waves.

Webb6 maj 2024 · As P-waves encounter the liquid outer core, which is less rigid than the mantle, they slow down. This makes the P-waves arrive later and further away than would be expected. The result is a P-wave shadow zone. No P-waves are picked up at seismographs 104° to 140° from the earthquakes focus. Figure 1. How P-waves travel …
