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

Earth’s core is located below the middle layer called the mantle and the outer layer –or crust. It consists of two main parts ...

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 ...

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

Research on hidden structures deep within Earth’s mantle challenges theories about our planet’s middle layer and could ...

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 ...

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 ...

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.
