Recent scientific discoveries reveal two extraordinary phenomena that could change our understanding of Earth's hydrology.
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 ...
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 ...
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 ...
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 ...
