Buried more than 3,000 miles beneath our feet, Earth’s solid inner core was once thought to be unchanging—locked in place at ...

Researchers have discovered cratonic thinning occurring beneath North America, driven by the remnants of the Farallon Plate. Researchers have discovered that the underside of the North American ...

It’s not much of a stretch to say that Earth’s inner structure, especially the innermost spherical core, has stupefied ...

Far be it from us to suggest there’s a parallel between the continental plate’s behavior and what is happening on top, but ...

Where the Earth’s core meets the mantle, there are two giant regions that have baffled geologists for fifty years. A new piece of the puzzle has now emerged with the discovery that they have ...

Surprising differences in the two so-called Large Low-Velocity Provinces may risk instability in Earth's protective magnetic field.

The mantle is the region between Earth’s core and crust. The fact that the isotope can still be found in rock and magma suggests that it must have somehow become trapped in the Earth. “This argument ...

This inner core is surrounded by a liquid outer shell of the same composition, enclosed by the mantle—a thick layer that begins about 30 kilometers beneath the Earth's surface and extends to a ...

The next layer is the mantle, which makes up most of Earth's volume and is composed of dense, semi-solid rock. Then there is the outer core, made of liquid metal, and the inner core, a solid ball ...

Seismic mapping of North America has revealed that an ancient slab of crust buried beneath the Midwest is causing the crust ...

New research led by a York University professor sheds light on the earliest days of Earth's formation and potentially calls ...
