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 ...

A team of geologists and mineral physicists at Harvard University, the University of California, Argonne National Laboratory and the University of Chicago has found evidence via lab experiments that ...

The Earth is made up of different layers: Therefore, instead of tectonic plates moving because of the convection currents, evidence suggests it is the plates that drive the convection. Slab pull ...

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 rotation speed and shape of Earth's deepest layer has been experiencing some surprising changes. Best of CES 2025 Awards ...

Earth’s innermost layer is a hot, solid ball of metal surrounded by a liquid metal outer core. For decades, planetary scientists suspected that the solid inner core deformed over time as it spun.

This article was originally published with the title “ The Plastic Layer of the Earth's Mantle ” in Scientific American Magazine Vol. 207 No. 1 (July 1962), p. 52 doi:10.1038 ...

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 ...
