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 ...

That’s relevant for digging through the Earth, because when a hole is dug or drilled, the walls along the sides of the hole are under tremendous pressure from the overlying rock, and also unstable ...

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 ...

A new Stanford University study has uncovered a puzzling global phenomenon that challenges long-held assumptions about Earth's geological history. The research, published in Earth-Science Reviews ...

Over time, Earth's interior—which is made mostly of silicate rocks and metals—differentiated into four layers. At the planet's heart lies the inner core, a solid sphere of iron and nickel that ...

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 ...

For spectators, total solar eclipses – such as the one that dazzled millions in April across North America – represent ...

Image caption, Without the ozone layer, planet Earth would be a very different place. One of those is the ozone layer. It’s basically the Earth’s sun cream - it protects the planet from ...

The ozone layer is a thin shield of gas in the Earth’s atmosphere that protects the planet, absorbing the sun’s ultraviolet (UV) rays and helping to preserve all life on the planet.
