The Mid-Atlantic Ridge is the longest mountain range on Earth

This underwater rift mountain chain runs for roughly 16 thousand kilometres

Snaking along the floor of the Atlantic Ocean, the Mid-Atlantic Ridge is a continuous underwater mountain range formed by tectonic plate divergence. It stretches from the Arctic Ocean down to the southern tip of Africa. Most of its peaks lie deep underwater, though Iceland forms a visible surface section.
