Earth inner core cooling

WebThe Earth is composed of four different layers. Many geologists believe that as the Earth cooled the heavier, denser materials sank to the center and the lighter materials rose to the top. Because of this, the crust is made of the lightest materials (rock- basalts and granites) and the core consists of heavy metals (nickel and iron). WebSep 11, 2024 · As Earth cooled over time, the temperature at the center of the planet eventually dropped below the melting point of iron at extreme pressures, and the inner core started to crystallize. Today, the inner core continues to grow at roughly 1mm in radius each year, which equates to the solidification of 8,000 tonnes of molten iron every second.
