The findings -- published today in the journal Nature Geoscience-- also may explain some deep earthquakes, hint that Earth's interior is hotter than believed, and suggest why partly molten rock or ...

The research into what lies deep, deep beneath our feet has yielded precious few details over the past few decades. We all grew up learning that we live on the Earth's crust, which is just a thin ...

The beginnings of a strange layer of molten rock deep inside the Earth may have finally been figured out by geoscientists. This layer, known as the D" layer, is about 1,900 miles underneath the ...

A new study from a University of Chicago scientist suggests there may be a layer of surprisingly fluid rock ringing the Earth, at the very bottom of the upper mantle. The finding was made by measuring ...
