If you were to slice through it, you would see the Earth is divided into distinct layers. On top is the relatively thin crust where we live. Beneath that is the 2,900 km thick mantle layer. Then, ...

Deep beneath our feet, far below the crust and mantle, Earth’s metallic heart is not as sealed off as geologists once assumed. New research indicates that gold and other precious metals are slowly ...

To understand the mantle—the largest layer of Earth’s rocky body—scientists drill deep cores out of the Earth. Scientists drilled the deepest core yet and recovered serpentinized peridotite that forms ...

Seismic waves created by earthquakes as they travel through the planet’s interior change speed and direction as they move through different materials. Things like rock type, density, and temperature ...

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 at Göttingen University have uncovered new evidence that some of Earth's most precious metals began their journey far deeper than once thought. Working with volcanic rocks from ocean ...

History was made this month. No, not another indictment, or a candidate throwing a hat into the presidential race. For the first time, a drill penetrated into the Earth’s mantle and retrieved samples ...

Back in my day, there were only four layers of Earth: the crust, mantle, liquid outer core and solid inner core. Now, scientists have revealed a new, distinct layer within our planet’s inner core, ...
