Geologists today have a good understanding of Earth's interior, based on pioneering work by Isaac Newton and Danish seismologist Inge Lehmann in the late 17th century and early-to-mid 20th century, ...

This layer makes up the majority of the inside of the planet. It is located underneath the crust but around the core. It makes up 84% of the total volume of the earth and is around 1,800 miles thick.

We finally know where two giant blobs in Earth's middle layer came from — and they're a mismatched pair. These strange regions in Earth's mantle, known as "large low velocity provinces" (LLVPs ...

Our planet, Earth, is structurally composed of a series of concentric internal spherical layers that are divided into: crust, upper mantle, mantle, outer core and inner core. Every ...

Water leaking into the Earth may be wrapping the core in crystals, a study has suggested. The study may help explain a weird area in the outer core that has long puzzled scientists.

Normally, younger rocks are deposited above older ones, forming predictable geologic layers. In the North Sea, this process ...

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 ...

An illustration depicting the layers of Earth's internal structure.. Earth's solid inner core may not be solid after all — at least not all the way through. Instead, it’s a hodgepodge ...

Like most of us, Earth has a lot going on under the surface — even in what may have once seemed to be its most unassuming layer. The mantle, a zone between our planet’s thin crust and the ...
