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 ...

Geoscientists have made an unprecedented achievement on their 60-year quest to know more about Earth's mysterious depths. Pieces of Earth’s rocky mantle were collected by a drilling vessel called the ...

To find a modern analog that may help explain the origins of life on Earth, scientists are searching under the sea, specifically, where rocks from the Earth’s mantle are exposed in direct contact with ...

When a magnitude 8.0 earthquake rattles a remote corner of the Pacific, the initial jolt lasts only seconds. But the planet ...

Unsustainable irrigation and drought have emptied nearly all of the Aral Sea’s water since the 1960s, causing changes extending all the way down to Earth’s upper mantle, the layer beneath the planet’s ...

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. Researchers had previously identified ...

Late last year, scientists in New Zealand announced that they had created the most thorough map of any continent on planet Earth. For decades, the geologists had dug up and analyzed countless rock ...

A new study suggests there may be a layer of surprisingly fluid rock ringing the Earth, at the very bottom of the upper mantle. A new study from a University of Chicago scientist suggests there may be ...

For 60 years, scientists have tried to get rock samples of the Earth’s mantle. But the geologic layer below the planet’s crust is incredibly difficult to reach. Scientists believe they’ve successfully ...
