Scientists now know how to drill deep enough to tap into an energy supply that would power the world for more than 20 million years if we capture just 0.1 percent of it.

Two enormous, supercontinent-sized 'islands' buried deep within the mantle have been revealed ... to be enriched in subducted oceanic crust, implying that Earth's recent subduction history is ...

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 ...

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

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 ...

But space exploration has still raised more questions than it answers. Mars' crust is stiffer than Earth's, its mantle less viscous. There's so much iron that its mantle is dominated by garnet ...

The substance can contain up to 1.5 percent water, and if the ringwoodite under the surface has just one percent water in its ...

China’s Chang’e 6 mission uncovers evidence of a molten lunar magma ocean and a violent ancient impact.
