Earth's deep mantle stored enough water in rocks to equal one ocean during our planet's early molten days, helping explain ...

When Earth was a molten inferno, water may have been locked safely underground rather than lost to space. Researchers ...

With modern seismic tomography, Earth scientists have discovered that above Earth's core-mantle boundary (CMB), about 2,900 ...

If we took a journey from Earth's surface to the center, the midway point locates roughly at 1900 km depth in the lower mantle. The lower mantle ranges from 660 to 2900 km depth and occupies 55% of ...

Earth’s deep interior still shapes the world above your feet. Water trapped far below the surface helps control how rocks ...
