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 ...

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 ...

The layer, located 100 miles below the Earth's surface, could help shed light on how the tectonic plates move. Reading time 2 minutes Earthquakes and volcanic eruptions are a result of the movement of ...

The lithosphere — the outermost layer of the Earth — has long been assumed to be composed largely of solid rock. But a recent ...

The research into what lies deep, deep beneath our feet has yielded precious few details over the past few decades. We all grew up learning that we live on the Earth's crust, which is just a thin ...

Hell, or something like it, may be a little closer than we thought. As a new study published in Nature Geoscience reveals, geologists at Cornell and the University of Texas have discovered a “hidden” ...

Scientists have discovered a new layer of partly molten rock under the Earth's crust that might help settle a long-standing debate about how tectonic plates move. The molten layer is located about 100 ...

A recently published study has revealed a little-known tectonic process unfolding beneath Turkey’s Central Anatolian Plateau, where part of the Earth’s crust is “dripping” deep into the planet’s ...

Prefer Newsweek on Google to see more of our trusted coverage when you search. Earth's inner layers have just got a bit more complicated, with scientists discovering a whole new inner core within the ...

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 ...

Geology runs in order, as sediments pile up over time, with older material buried deeper and younger layers added on top. The sequence allows scientists to read Earth’s past like a timeline. It ...
