The longest mountain range in the world is the Andes. Stretching over 7,000 kilometers along the western edge of South America, the Andes traverse seven countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina. This remarkable range is home to diverse ecosystems and climates, from tropical rainforests to glaciers. The Andes also boast some of the world's highest peaks, including Aconcagua, which stands at 6,960 meters (22,837 feet). The mountains play a crucial role in the continent's culture, economy, and biodiversity, influencing weather patterns and serving as vital resources for indigenous peoples.
