Gigantic hidden fortresses discovered 1,800 miles underground in Earth's mantle, rewrite how the planet's interior works.

Geologists discovered "gigantic fortresses" under the Earth's crust, which have provided insight into the workings of the ...

The magnetized rocks of Earth's crust and mantle, also known as the upper lithosphere, accounts for generating 6 percent of ...

The origins in question, researchers believe, could be the BLOBS found deep within the Earth. These mysterious structures ...

Earth's crust may "drip" into its middle layer under growing mountain ranges. This odd process, called lithospheric dripping, has been proposed to occur under the Andes, in Central Asia, in the U ...

In 1981, Scientists discovered the thinnest portion of the Earth’s crust — a 1-mile thick, earthquake-prone spot under the Atlantic Ocean where the American and African continents connect. This is ...

The mantle makes up the bulk of Earth’s interior and lies between Earth’s dense, super-heated core and its thin outer layer, the crust. The mantle is about 2,900 kilometers -- or 1,802 miles thick -- ...

Hidden inside the Earth—within the first several hundred kilometers below the crust—there is another ocean. It is, most likely, the largest ocean in the world.

Earth's crust once formed a dense "root" supporting Colombia's northern Sierra Nevada de Santa Marta mountains, but new research suggests this prop sank into the mantle millions of years ago.
