It’s not much of a stretch to say that Earth’s inner structure, especially the innermost spherical core, has stupefied scientists for generations. It sits over 3,000 miles below the surface, smaller ...

The mantle is incredibly difficult to study because it’s so deeply buried beneath the Earth’s crust, or outer skin. Now, scientists have drilled a 1,268m-deep core that reaches down into this ...

Surprising differences in the two so-called Large Low-Velocity Provinces may risk instability in Earth's protective magnetic field.

The Keeble Observatory at Randolph-Macon College holds weekly public viewing during spring semester. Check their website ( or ...

Solid Earth sciences encompass the study of the crust, mantle and core of the Earth and other rocky planetary bodies. Earth sciences include petrology, mineralogy, seismology, core studies ...

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 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 ...

The mantle is the region between Earth’s core and crust. The fact that the isotope can still be found in rock and magma suggests that it must have somehow become trapped in the Earth. “This argument ...

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 ...
