Stanford researchers have created the first-ever global map of a rare earthquake type that occurs not in Earth's crust but in ...

Geologists have spent decades trying to punch through Earth’s crust to reach the mantle, the vast rocky layer that makes up ...

The Earth with the upper mantle revealed. Researchers at The University of Texas at Austin have discovered a previously unknown layer of partly molten rock in a key region just below the tectonic ...

Like a moth in a cocoon, the metamorphosis of Earth's crust from molten goop to solid land is hidden from view, leaving scientists to guess at how the eons-long process unfolds. Using nearly four ...
