Explanation:
There are no samples of the Earth's core available for direct measurement, as there are for the Earth's mantle. Information about the Earth's core mostly comes from analysis of seismic waves and the Earth's magnetic field. The inner core is believed to be composed of an iron–nickel alloy with some other elements.
