Ancient Australian rocks suggest Earth’s continents formed later than expected and share a common origin with the Moon.

Deep below Earth's surface lie two gigantic structures with mysterious origins. Now, seismologists have found new clues about their composition that could upend our understanding of the whole planet's ...

Researchers at Göttingen University have uncovered new evidence that some of Earth’s most precious metals began their journey far deeper than once thought. Working with volcanic rocks from ocean ...

Earth’s deep interior still shapes the world above your feet. Water trapped far below the surface helps control how rocks move, melt, and recycle through the mantle.

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

An ancient slab of Earth's crust buried deep beneath the Midwest is sucking huge swatches of present-day's North American crust down into the mantle, researchers say. The slab's pull has created giant ...

Today, oceans cover about 70% of Earth’s surface. This stark contrast has long driven scientific interest in how water managed to survive Earth’s transition from an early molten state to a largely ...

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

This surprising study reveals that the “secret water vault” within Earth is one of the most consequential geological ...

Far beneath us, large low shear velocity provinces (LLSVPs) and ULVZs under Africa and the Pacific at Earth's core-mantle ...

All the activity on Earth’s surface — erupting volcanoes, shifting tectonic plates, restless seas and myriad forms of life — depends on the two-part engine under the hood. Directly beneath Earth’s ...

Chinese scientists have found evidence that Earth’s deep mantle stored vast amounts of water billions of years ago, reshaping ...
