Earth’s core cooling faster than expected

A critical tectonic process between the core and surface layers may be shut down earlier than anticipated

The Earth’s molten interior is cooling faster than expected, which could turn the planet into a cold, inactive world similar to neighboring Mercury and Mars sooner than previously thought, researchers have warned.

The study, published in the Earth and Planetary Science Letters journal, examined how well bridgmanite – the primary mineral found at the boundary between the planet’s core and mantle layers – conducts heat from the hot, molten core to the surface.
