Deep within Earth, there lies a mysterious layer called the D" layer. Located roughly 3,000 kilometers down, this zone sits just above the boundary between the planet's molten outer core and its solid ...

Scientists discovered plate anomalies in Earth's mantle using seismic wave analysis. These mysterious structures challenge tectonic theories.

thermal characteristics (temperature changes), chemical composition, movement, and density. Each of the layers are bounded by "pauses" where the greatest changes in thermal characteristics, chemical ...

The Earth with the upper mantle revealed. Researchers at The University of Texas at Austin have discovered a previously unknown layer of partly molten rock in a key region just below the tectonic ...

There's a lot more to Earth than meets the eye. Far from being just a roundish rock barreling through space, our planet is composed of several layers held together by intense forces of gravity. Our ...

At the center of our planet is a very hot rotating ball of mostly iron and nickel (sorry Journey to the Center of the Earth fans). Scientists infer features of this innermost geographic layer—like the ...
