An ancient slab of Earth's crust buried deep beneath the Midwest is sucking huge swatches of present-day's North American crust down into the mantle, researchers say. The slab's pull has created giant ...

In 1981, scientists discovered one of the thinnest portions of the Earth’s crust — a 1-mile (1.6 kilometers) thick, earthquake-prone spot under the Atlantic Ocean where the American and African ...

Picture the Earth’s crust and you most probably think of dense, dry rock. You don’t imagine a goey, honey-like substance trickling down into the planet’s deep underbelly. And yet, new research has ...

Just when things couldn't get any crazier in the US, scientists have discovered that the underside of the Earth's crust is dripping molten lava inside the planet. The hot lava is thought to be ...

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 ...

What is the chemical composition of the Earth’s interior? Because it is impossible to drill more than about ten kilometres deep into the Earth, volcanic rocks formed by melting Earth’s deep interior ...

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 ...

The Earth's mantle might not always move along in lockstep with the overlying tectonic crust—as set out in science textbooks for decades—but may instead behave differently. This is the conclusion of ...
