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 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 ...

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 hole in the ozone layer over Antarctica only grew to 22 million square kilometres this year, the smallest observed since ...

In a surprising twist on our planet’s ancient history, scientists are now suggesting that Earth might once have had a ring ...

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 ...

By the time of the moon-forming impact, the Earth was already separated into these rock and metal layers. However, the intense force and heat of the impact re-melted the proto-Earth, re-mixing the ...

The Earth consists of three layers: crust, mantle, and core. The Earth's crust is the outermost layer of the planet, consisting of solid rock that forms the Earth's surface. The mantle is the semi ...

Yet, that is what some researchers at NASA did a few years ago. Atmospheric physicists Paul Newman and Luke Oman built a simulation of the Earth’s atmosphere and then proceeded to strip away our ...

Many parts of Earth are covered and protected by a layer of organisms called a biocrust. The layer acts as a skin for the Earth, protecting landscapes and reducing long-term damage. But climate ...

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 ...
