The world's longest above-water mountain range is the Andes, about 7,000Â km (4,300Â mi) long. The range stretches from north to south through seven countries in South America, along the west coast of the continent: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina. Aconcagua is the highest peak, at about 6,962Â m (22,841Â ft).
This list does not include submarine mountain ranges. If submarine mountains are included, the longest is the global mid-ocean ridge system which extends for about 65,000Â km (40,000Â mi).
