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 ...
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 ...
Scientists have always been curious about the atmosphere surrounding us, but in the past, they could not just hop on a spaceship to see what was up there. Instead, scientists hiked up high ...
The Earth has a layered structure made up of the core, the mantle and the crust. Different elements are present in different parts of the Earth’s structure. The crust is made from enormous ...
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 ...
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 ...
A team of researchers has found pollutant metals in Earth's stratosphere — the second layer of our atmosphere — and traced them back to rockets and satellites. "There are so many rockets going ...
After this mixing, the Earth was still hot enough for separation to occur again and form new rock and metal layers - this is the key to dating when the moon formed! When rock and metal mix, they are ...
