No one knows why the river of liquid iron flowing 1,400 miles beneath our feet just reversed course.

A river of molten iron, more than 2,000 kilometers below the surface, appears to have pulled off something Earth scientists did not expect. Around 2010, a broad patch of fluid in the outer core ...

ESA satellites detected a dramatic reversal in Earth’s molten core flow beneath the Pacific, revealing unexpected changes ...

Scientists discovered a mysterious reversal in Earth’s molten core flow beneath the Pacific using satellite data from space.

South African diamonds have revealed nickel-rich metallic inclusions, offering the first direct evidence of reactions predicted to occur deep in Earth’s mantle. The study shows how oxidized melts ...

IMAGE: This artistic view of the Earth’s interior shows hydrocarbons forming in the upper mantle and transported through deep faults to shallower depths in the Earth’s crust. The inset shows a… Click ...

Scientists have created a global “treasure map” for rare earth elements by uncovering where the strange volcanic rocks that ...

Seismic imaging has exposed two massive zones hidden deep in Earth’s mantle. These giant blobs, known as large low-velocity provinces, or LLVPs, stretch beneath Africa and the Pacific. They are so ...

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 ...

As one considers the deepest parts of our planet, it would seem likely that such depths should be distributed randomly around the Earth’s surface, with perhaps some deep abysses located along the ...
