Earth's Core Cooling Faster Than Thought | Texas News
Earth’s core is cooling twice as fast as scientists once believed, thanks to new findings about the mineral bridgmanite—our planet’s most abundant lower mantle material. This mineral, thought to insulate heat, actually conducts it more efficiently under extreme pressure, reshaping models of heat transfer. The accelerated cooling directly impacts plate tectonics, volcanic activity, and the longevity of Earth’s magnetic field—our shield against solar radiation. Using diamond anvil cells to mimic deep-Earth conditions, researchers are now piecing together how these hidden processes shape our…
