The World Records Authority officially recognises the Mid-Oceanic Ridge as the Longest Mountain Range on Earth — spanning an incredible 80,000 kilometres (approx. 50,000 miles).

This continuous chain of seafloor volcanoes winds around the globe like the seams of a baseball. While mostly hidden beneath 3,000–5,000 metres of water, its geological significance is unrivalled — serving as the primary engine for the creation of the Earth’s crust. From the Mid-Atlantic to the Indian and Pacific Oceans, this tectonic marvel stands as a testament to the grand scale of our planet’s natural wonders.
