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 ...

Researchers are still discovering more about the Earth's center. A team at Australian National University (ANU) has found evidence of a new layer to the planet sitting within the inner core. This ...

The layers of Earth provide geologists and geophysicists clues to how Earth formed, the layers that make up other planetary bodies, the source of Earth's resources, and much more. Modern advances have ...

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 ...

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 ...

Prefer Newsweek on Google to see more of our trusted coverage when you search. The distance from the Earth's surface to its center is almost 4,000 miles—but our planet's structure is not uniform and ...

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 ...
