Scientists discover ‘lubricant’ for Earth’s tectonic plates

This finding could help scientists better understand the fundamental geological functions of the planet, as well as improve their knowledge of volcanism and earthquakes.

Scientists from the University of California at San Diego have discovered a “lubricant” for Earth’s tectonic plates.

According to scientists at Scripps Institution of Oceanography, a layer of liquefied molten rock in the Earth’s mantle may be acting as a lubricant for the sliding motions of the planet’s gigantic tectonic plates. This finding could help scientists better understand the fundamental geological functions of the planet, as well as improve their knowledge of volcanism and earthquakes.
