Researchers at Göttingen University have uncovered new evidence that some of Earth’s most precious metals began their journey far deeper than once thought. Working with volcanic rocks from ocean ...

Geologists have spent decades trying to punch through Earth’s crust to reach the mantle, the vast rocky layer that makes up most of the planet’s volume. In 2023, an international team working from a ...

To learn about how rocks and minerals get pushed from the Earth's mantle to the seafloor, scientists drilled a really, really deep hole. Reading time 3 minutes Rock at the bottom of the Atlantic Ocean ...

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 ...

The boundary zone between Earth's molten metal core and the mantle, its rocky middle layer, might be a diamond factory. A new laboratory experiment finds that, under extreme temperatures and pressures ...

If you were to slice through it, you would see the Earth is divided into distinct layers. On top is the relatively thin crust where we live. Beneath that is the 2,900 km thick mantle layer. Then, ...

The center of the Earth is almost 4,000 miles (6,400 kilometers) beneath our feet. To put that into context, the deepest humans have ever drilled is 7.6 miles (12.2 km) down, and it took geologists ...

Here’s what you’ll learn when you read this story: 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 ...
