Scientists at Stanford have unveiled the first-ever global map of rare earthquakes that rumble deep within Earth’s mantle rather than its crust. Long debated and notoriously difficult to confirm, ...

Antarctica sits above the strongest negative gravity anomaly on Earth, a region where the planet’s gravitational pull dips so ...

Add Yahoo as a preferred source to see more of our stories on Google. To understand the geologic processes roiling beneath the Earth’s crust, it helps to have samples of what exactly is going on down ...

First global map of mantle earthquakes reveals seismic activity far beneath continents, challenging old ideas about Earth’s ...

Scientists now believe vast water reserves are hidden nearly 400 miles beneath Earth's surface, locked within rock. Lab ...

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 ...

On present-day Earth, plate subduction continuously modifies the chemical composition of the convecting mantle, and various mantle sources linked to these processes have been widely studied. However, ...

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

Most diamonds are made of carbon recycled over and over again between Earth’s surface and its crust. But diamonds with the deepest origins — such as the famed Hope Diamond — are made of carbon from a ...
