WebComposition [ edit] Thickness of Earth's crust (km) Abundance (atom fraction) of the chemical elements in Earth's upper continental crust as a function of the atomic number. The rarest elements in the crust (shown in yellow) are not the heaviest, but are rather the siderophile (iron-loving) elements in the Goldschmidt classification of elements. WebJan 20, 2024 · The inner core is solid, while the outer core is liquid. This phase difference probably reflects a difference in pressure and composition, rather than one of temperature. Density estimates obtained from seismological studies indicate that the core is metallic, and mainly iron, with 8-10 percent of lighter elements.
