The Earth's interior is composed of four layers, three solid and one liquid—not magma but molten metal, nearly as hot as the surface of the sun. The deepest layer is a solid iron ball ...

Earth’s core is pretty dynamic. Its spin speeds up and slows down based on how its two primary layers are behaving ... Laura is a science news writer, covering a wide variety of subjects ...

Researchers studying decades of earthquake data say they have found the first evidence that, in addition to spinning backward ...

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.

The surface of Earth's inner core appears to be dynamic, changing shape as it rotates, earthquake waves reveal.

Earth science concentrates on investigating how the planet works and why. This field delves into the many layers of the Earth and explains how those pieces fit together into a cohesive structure.

The work has been published in Progress in Earth and Planetary Science. Using a new data-assimilation ... Being able to study the interactions of these layers vertically and around the globe ...

Earth's interior is made up of a series of layers that sit below the surface crust. In order of depth, these layers include the solid, but flowing mantle, the liquid outer core and the solid iron ...
