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.

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 ...

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 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 ...

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 ...

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