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 ...

Some 4.6 billion years ago, Earth was nothing like the gentle blue planet we know today. Frequent and violent celestial impacts churned its surface and interior into a seething ocean of magma—an ...

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

With findings on Earth’s polar extremes and its innermost core, scientists shaped how we look at the planet in 2025 in ...

Far below the oceans and continents we know, Earth’s deep mantle appears to have stored far more water in its early history than scientists once imagined. New experimental work on high‑pressure ...

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

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 ...

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

D heat maps show how deep temperature patterns under Greenland help explain uneven ice loss and land motion, improving future ...

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 ...

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 ...
