Buried nearly 1,800 miles below Earth’s surface are two vast, continent-sized structures that continue to challenge our ...

Deep inside Earth, far below the crust and mantle we learn about in school, scientists are mapping strange, continent-sized structures that appear to shape everything from volcanic hotspots to the ...

Deep beneath your feet, far beyond where any drill can reach, something strange is hiding. Two continent-sized blobs of rock sit just above Earth’s core, hot, dense and stubbornly different from ...

Continents drift apart in slow, powerful motions that reshape the world above and below your feet. A new study now shows that ...

Atoms found deep inside our planet argue that parts of “proto-Earth,” the early version of our planet, still survive inside the mantle.

An international team has made a significant breakthrough in understanding the tectonic evolution of terrestrial planets.

On a time scale of tens to hundreds of millions of years, the geomagnetic field may be influenced by currents in the mantle. The frequent polarity reversals of Earth's magnetic field can also be ...

Southwest Research Institute’s Dr. Simone Marchi collaborated on a new study finding the first geophysically plausible scenario to explain the abundance of certain precious metals — including gold and ...

The evolution of our Earth is the story of its cooling: 4.5 billion years ago, extreme temperatures prevailed on the surface of the young Earth, and it was covered by a deep ocean of magma. Over ...
