The thermal structure of the Earth's lowermost mantle—the D″ layer spanning depths of ∼2,600–2,900 kilometres1—is key to understanding the dynamical state and history of our planet.

COOK1 has shown that, in the Earth's gravitational potential when developed into a series of zonal spherical harmonics, the coefficients are influenced to the fourth harmonic by the ...

The interior of the Earth, like that of the other terrestrial planets, is chemically divided into layers. The Earth has an outer silicate solid crust, a highly viscous mantle, a liquid outer core ...

The Earth has a layered structure made up of crust, mantle, outer core and inner core. Find out more in this BBC Bitesize guide for students aged 11-14.

In the early 1990s, eight people tried to survive in a hermetically sealed glass structure filled with miniature forests, ...

The structure of earth is in spherical form and is composed of four layers, three solid and one liquid which is in the form of molten metal, and is hot as the surface of the sun. A fruit such as a ...

Our universe is vast and getting larger every day, but humanity's understanding of the cosmos is growing too. Tour the universe from the Big Bang to planet Earth in this SPACE.com infographic series.

The distance from the Earth's surface to its center is almost 4,000 miles—but our planet's structure is not uniform and is actually made up of several different layers, some of which are hotter ...

The Earth system models use different hypotheses for this purpose. “We analyze whether the patterns we see are described correctly by the models,” says Reichstein. The studies from Jena show that, ...

Mysterious 'donut' structure is discovered hidden inside Earth's core - and it could unlock the secrets of our planet's protective magnetic field.
