Scientists have discovered yet another layer deep inside the core of the Earth, a new study suggests. "Traditionally we've been taught the Earth has four main layers: the crust, the mantle, the outer ...

Scientists believe that gold and other precious metals are slowly leaking to the surface from Earth's core through Hawaiian ...

Scientists have long wondered what lies at the very center of the Earth, and the latest research is putting weight behind a theory that our planet has a distinct ball of iron within its metallic core.

Seismic data from Antarctica has revealed a vast, thin layer draped along the boundary between Earth's core and mantle, ...

Deep within Earth’s core, scientists are uncovering signs of a hidden structure that challenges long-standing models of the planet’s interior.

Two new seismic studies suggest Earth's core is more complex than previously thought, revealing both a possible 'innermost inner core' and widespread ultralow velocity zones along the core-mantle ...

One of geology’s basic principles is that the Earth is made up of four layers: the crust, the mantle, the outer core, and the inner core. But this may be squashed in light of a new study that suggests ...

The Earth with the upper mantle exposed. Researchers at The University of Texas at Austin have discovered a previously unknown layer of partly molten rock approximately 100 miles beneath the Earth's ...
