Scientists say the oxygen you just breathed in was once the deadliest poison on the planet, released by tiny microbes that accidentally wiped out most of the life around them in what geologists call the Great Oxidation Event

There is more freshwater locked inside the rocks of Earth’s mantle than in every river, lake, and surface reservoir on the planet combined, hidden in a mineral called ringwoodite hundreds of miles beneath your feet

The smell of the ocean — that sharp, clean scent people travel thousands of kilometres to breathe — is not salt, which has no real smell, but partly dimethyl sulphide: a sulfur gas released when compounds made by microscopic marine algae are broken down by bacteria, death, and grazing in the sea.

In 2004, paleontologists digging in the Canadian Arctic unearthed the fossil of a 375-million-year-old creature named Tiktaalik that possessed both the scales of a fish and the sturdy, jointed limb bones of a land animal—and this single, perfect transitional fossil bridged the evolutionary gap between water and land, showing the exact moment our distant ancestors began to crawl out of the sea.

Nobody talks about why the Himalayas are still getting taller, and it isn’t erosion slowing down or new rock forming, it’s that India is still ramming into Asia at roughly the speed your fingernails grow

Nearly three kilometres beneath a Canadian mine, geologists found water that may have been isolated in the rock for roughly two billion years — older than animals, plants and almost everything we think of as complex life. The brine was so salty and bitter that, when one researcher tasted it, she was sampling a flavour shaped by a world humans never knew

The ocean produces roughly half of Earth’s oxygen — not the rainforest, which uses up most of what it makes — through photosynthesis by phytoplankton, microscopic marine organisms so abundant that a single teaspoon of seawater can contain as many as a million of them.

Earth’s largest waterfall is hidden underwater in the Denmark Strait between Iceland and Greenland, where dense cold water plunges about 3,500 meters down the seafloor, far exceeding any waterfall on land in drop height and volume

Your own voice sounds different to other people than it sounds to you, because the version you hear is reaching your inner ear partly through the bones of your skull, which amplify lower frequencies that everyone else cannot hear — and the recorded version that strikes most people as alien when they first hear it is in fact the only version of their voice anyone else has ever known
