Think twice before stepping on that crunchy top layer of soil.
The cycles of life all rely on the dynamism of the Earth's crust.
Each year, several trillion pounds of microscopic silicon-based skeletons fall down the water column to pile up into siliceous ooze.
Passing chunks of ice can fertilize ocean waters and play a role in the planet’s carbon cycle.
On Earth, carbon can form millions of compounds, while silicon is largely stuck inside rocks. But elsewhere, silicon could form the basis of life.
1859's Carrington event gave us a preview of how catastrophic the Sun could be for humanity. But it could get even worse than we imagined.
Life largely owes its existence to this equation. Be sure to hug your house plant today.
In 774/775, tree rings show a spike in carbon-14 unlike anything else. At last, scientists think they know why. Every once in a while, science gives us a mystery that comes […]
If you thought that diamonds were the hardest things of all, this will have you thinking again. Carbon is one of the most fascinating elements in all of nature, with chemical […]
The two planets most suited for habitability had very different fates. At last, scientists know why. Imagine the early days of our Solar System, going back billions of years. The Sun […]
