The longest mountain range in the world is the Andes.
The Majestic Andes Mountains
Stretching approximately 7,000 kilometers (4,300 miles) along the western edge of South America, the Andes is the longest continental mountain range on Earth. This vast mountain system traverses seven countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina. It is a region of remarkable geological and biological diversity, featuring towering peaks, active volcanoes, and a wide array of ecosystems.
The Andes play a vital role in regulating South America's climate and water resources, with glaciers and snowmelt feeding numerous rivers. This range is also a global biodiversity hotspot, home to thousands of unique plant and animal species.
Ranking the World's Longest Mountain Chains
When considering the most prominent above-ground mountain ranges, the Andes stands out due to its immense length. Here is a comparison of some of the longest mountain chains found across the globe:
