Earth inner core cooling
WebJan 14, 2024 · This suggests that the heat flow from the core into the mantle is also higher than previously thought. Greater heat flow, in turn, increases mantle convection and accelerates the cooling of the Earth. WebJul 20, 2015 · The outer core is an iron-and-nickel alloy that serves as a buffer between the inner core and Earth's mantle, a layer of magma and molten rock. The inner core is a solid, iron-rich ball that's about 750 miles (1,200 kilometers) thick and 1,802 miles (2,900 kilometers) below Earth's surface. ...
