1 Answer

Answer :

We do not know exactly because there is no way to get to it itfind out. We know the outer core composed mainly of a nickel-ironalloy.We believe that the composition of Iron meteorites must besimilar to that of the outer core and the the alloy in these rangesfrom 5% to 62% nickel from meteorite to meteorite with an averageof 5% nickel leaving 95% Iron.
