About 700 million years ago, massive glaciers crept across the Earth’s surface toward an ice-covered sea, scraping the ground ...

Experiments show that those small electrical charges can trigger the chemical reactions necessary to form organic molecules.

Iron can form compounds with helium at pressures as low as 5GPa – about 50,000 atmospheres – researchers in Japan report.

“This influx of elements changed ocean chemistry, at a time when more complex life was starting to evolve.” Kirkland and ...

Minerals swept up on land by this “glacial broom” altered marine chemistry and infused oceans with nutrients that they say ...

By the end of the Neoproterozoic, as Earth’s icy cover began to thaw, major chemistry shifts were taking place in Earth’s atmosphere and oceans. “The end of these glaciations is marked by ...

When satellites vaporise, they seed the stratosphere (the region of the atmosphere between 10km and 50km above Earth’s ...

Examples of this are the gas carbon monoxide, which consists of one carbon and one oxygen atom, or the nitrogen gas in the earth's atmosphere with its two nitrogen atoms. Chemistry recognizes ...
