About 1,800 miles (2,900 kilometers) below our feet, two enormous patches of strange rock sit above Earth’s core. New ...

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 ...

The entire outermost part of Earth is able to wander over the rest of the planet, and now researchers say in a new study detailed in the Nov. 8 issue of the journal Nature that they can explain how it ...

Two enormous structures that sit at the border between the Earth's mantle and its core have puzzled scientists for decades.

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

There is more to the Earth than what we can see on the surface. In fact, if you were able to hold the Earth in your hand and slice it in half, you'd see that it has multiple layers. But of course, the ...

While this new layer is difficult to observe, its existence may point to an unknown, dramatic event in Earth's history. Investigating the structure of the inner core can help us understand more about ...
