Heavy iron isotopes leaking from Earth’s core

Earth’s molten core may be leaking iron, according to researchers who analyzed how iron behaves inside our planet.

The boundary between the liquid iron core and the rocky mantle is located some 1,800 miles (2,900 km) below Earth’s surface. At this transition, the temperature drops by more than a thousand degrees from the hotter core to the cooler mantle.
