Is the inner core melted
Witryna23 lip 2024 · We conclude that the melting temperature of iron at the Earth's inner core boundary is ~5950 (400) K. The present study indicates a relatively gentle melting slope of iron and supports a young inner core age of ~0.565 Gyr inferred from paleomagnetic observations. Open Research References Citing Literature Supporting Information … WitrynaEstimates vary on how much heat crosses the core/mantle boundary, from 4 TW to 17 TW. Even the larger value is much, much smaller than the heat emitted by the Earth's surface. Estimates of the total heat flow from the interior of the Earth (core, mantle, crust) are much tighter, 46 TW ± 3 TW (Jaupart 2007) (cf 47 TW ± 2 TW (Davis 2010)).
