We finally know where two giant blobs in Earth's middle layer came from — and they're a mismatched pair. These strange regions in Earth's mantle, known as "large low velocity provinces" (LLVPs), are ...

Like straight out of Julio Verne's Journey to the Center of the Earth, scientists from Northwestern University and the ...

The next layer, the mantle, stretches about 1,800 miles (2,900km) below Earth's surface. The mantle contains both magma, or molten rock, and slowly-moving solid rock. Earth's innermost layer is ...

Scientists have long been puzzled by volcanoes that erupt far from the edges of tectonic plates—known as intraplate volcanoes ...

The Earth is made of different layers: the core, mantle and crust. Plate tectonic theory shows that the crust of the Earth is split into plates (pieces of the Earth’s crust). The movement of ...

Led by Curtin University geologists Chris Kirkland and Tim Johnson, a research team unearthed this primeval crater beneath ...

The Earth’s mantle, stretching up to 1,800 miles thick and making up a whopping 84% of the planet’s volume, used to be ...

The mantle of the Earth, up to 1,800 miles (2,900 kms) thick and 84% of the Earth's volume, was assumed to be a simple ...

The Earth is made up of different layers. The outermost is the crust, which is where we humans stand. The next layer is the mantle, which makes up most of Earth's volume and is composed of dense ...

Deep inside the mantle (the layer between Earth's iron core and its silica-dominated crust), there are vast areas beneath the Pacific Ocean and the African continent where seismic waves travel ...

Scientists uncover surprising evidence that the Kerguelen hotspot, responsible for the 5,000-kilometer-long Ninetyeast Ridge, ...
