WebIt is liquid and made predominantly of iron, a very much denser material than the rock materials in the mantle and crust, with small amounts of other elements. The Earth's magnetic field is a result of convection currents in this outer iron core. The dense inner core extends from 5,150-6,370 km (the remaining 19%) below the Earth's surface. WebSo that's why, when you look at the composition of the earth, you have the densest, the heaviest elements, at the center. And then the lightest elements are forming the …
