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 ...

Earth's crust ranges from 5 to 70 kilometers in thickness and serves as the planet's outermost layer. This thin shell represents less than one percent of Earth's total mass, yet it's the only layer we ...

A University of Liverpool scientist has discovered a new layer near the Earth's core, which will enable the internal temperature of the Earth's mantle to be measured at a much deeper level ...

Earth's inner layers have just got a bit more complicated, with scientists discovering a whole new inner core within the center of the planet. Research released on February 21 in the journal Nature ...

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.

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 ...

Researchers have detected a previously unknown layer of partially molten rock beneath Earth's crust. The discovery could help scientists learn more about the movements of Earth's tectonic plates, ...

Seismic waves passing through Earth's inner core have revealed much about our planet's iron center: how it's changing shape, reversing its spin, is weirdly textured, and contains an unusual state of ...

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 ...
