Where is the longest mountain range in the world?

The longest mountain range in the world is the Andes, which stretches over 7,000 kilometres (4,350 miles) along the western edge of South America. The Andes pass through seven countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina. The mountain range is home to diverse ecosystems, including high-altitude deserts, tropical rainforests, and glaciers. The Andes also contain some of the highest peaks in the world, including Mount Aconcagua, the highest point in both the Andes and the Western Hemisphere.
