The Andes Mountains primarily run through South America, extending along the western edge of the continent. They are the longest mountain range in the world, stretching over 7,000 kilometers (4,300 miles) across seven countries, including Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina. The Andes are known for their diverse ecosystems, rich biodiversity, and indigenous cultures. The mountains also play a crucial role in shaping regional climate and economy through agriculture and mining.
