Location of inner core
Witryna7 mar 2024 · The Earth has a solid inner core and a liquid outer core, both made of iron and nickel. The metal carries an electrical current that is powered by the movement of the liquid. The electrical current creates a magnetic field that reaches out from the core to the surface of the Earth and beyond. The magnetic field formed by the Earth’s core … WitrynaInnermost 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.
