WebbThe inner core spreads from the center of the Earth to 5100 km below the Earth’s surface. It is below the outer core and comprises iron and nickel. Though it is the innermost layer, it is present in the solid state because it is under high pressure from the weight of layers present above it.
The Iron of Earth
Webb9 mars 2024 · According to Lide (2006) the pressure in the inner core is 330 to 360 GPa, at which iron becomes a solid even at the high temperatures in the core. If you could drill as far as the core you would have to build a device that's able to withstand that pressure, because if you can't, the material surrounding your well would immediately become … WebbInnermost Inner Core. Travel-time anomalies of waves traversing the inner core indicate that the directional dependence of wave propagation within the inner core is generally fast for waves travelling in the north-south direction, and low for waves travelling in the equatorial plane. This is consistent with normal-mode splitting data. earthquake in turkey how to help
