The Challenger Deep plunges nearly eleven kilometers below sea level

The Challenger Deep plunges nearly eleven kilometers below sea level

In the Mariana Trench, the Challenger Deep reaches about 10,900 meters — deeper than Mount Everest is tall, measured from sea level to summit.

Temperatures near freezing and crushing pressure still allow amphipods, holothurians, and microbes to persist on sparse organic rain.

Earth’s deepest known spot is not barren rock alone. Even at eleven kilometers down, ecology finds a foothold on the planet’s basement floor.
