What is the longest mountain range in the world?

The Andes Mountains in South America form the longest continental mountain range in the world, stretching approximately 7,000 kilometres (4,350 miles). The range spans seven countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina. The Andes are home to a diverse array of ecosystems, from tropical rainforests to high-altitude deserts. They are also rich in natural resources and have been central to the cultures of ancient civilisations like the Inca.
