Important facts about inner core
WitrynaThose important for understanding the Earth’s interior are P-waves, (primary, or compressional waves), and S-waves (secondary, or shear waves), which travel through solid and liquid material in different ways. ... Indirect signals received in the P-wave shadow zone suggest there is a solid inner core deflecting some waves. Illustrations ... Witryna7 mar 2024 · 4. The outer core’s NiFe alloy is extremely heated. The temperature of the outer core is estimated to be around 3,000-4,500 K (2,700-4,200 °C; 4,900-7,600 °F) in its outer area. The temperature then nearly doubles at the boundary between the outer and inner cores, to about 4,000-8,000 K (3,700-7,700 °C; 6,700-14,000 °F).
