A new study of decades worth of seismogram data shows that the surface of Earth’s iron and nickel core is more malleable than scientists thought.

Where the Earth’s core meets the mantle ... representing a natural consequence of gravitational settling and the way the subducted crust is stirred through the mantle. That hasn’t stopped them ...

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 ...

Giant regions of the mantle where seismic waves slow down may have formed from subducted ocean crust, a new study finds.

Deep within Earth’s mantle lie two enormous, continent-sized structures known as LLVPs. Scientists once believed these ...

These results suggest that similar reactions between helium and iron may have occurred within Earth’s core shortly after its formation, trapping much of the primordial helium-3 in the material that ...

Scientists now know how to drill deep enough to tap into an energy supply that would power the world for more than 20 million ...

Others have suggested that the blobs are huge chunks of oceanic crust that were pushed into the mantle when one tectonic plate slipped under another — a process known as subduction. The crust ...

Scientists have uncovered new information about the Earth's core: it may not ... The outermost is the crust, which is where we humans stand. The next layer is the mantle, which makes up most ...

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 ...

A breakthrough study has provided the most detailed 3D look yet at the inner workings of the Tonga Subduction Zone, where ...
