Despite being composed of solid rocks, the Earth's mantle, which extends to a depth of ~2890 km below the crust, undergoes convective flow by removing heat from the Earth's interior. This process ...

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 ...

A record-breaking drilling attempt, which dug more than a kilometer into an underwater mountain in the Atlantic Ocean, has given scientists a treasure trove of rocks to study for clues to Earth's ...

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 ...

Researchers have combined numerical modeling of dislocation glide and results from diffusion experiments to revisit the rheology of wadsleyite, ringwoodite and majorite garnet under geological strain ...
