A massive ocean three times larger than all surface water combined is trapped inside Earth's mantle
A massive reservoir of water hidden 700 kilometers beneath the Earth's surface contains three times the volume of all our oceans combined, held within a rare mineral called ringwoodite.
Deep within the Earth's mantle transition zone lies a staggering amount of water trapped inside a blue, sponge-like mineral known as ringwoodite. This reservoir is so vast that it triples the volume of every ocean on the planet's surface. Scientists confirmed its existence by analyzing seismic waves, which slow down significantly when passing through this hydrated rock layer.
