The Andes is the longest mountain range in the world, stretching over 7,000 kilometers along the western edge of South America. It runs through seven countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina. The range is known for its diverse ecosystems, including tropical rainforests, high-altitude deserts, and glaciers. The Andes is home to many unique species of plants and animals, as well as indigenous cultures that have lived in the region for thousands of years. The mountains also contain significant mineral resources, making them important for mining activities. Popular activities in the Andes include hiking, skiing, and exploring ancient ruins.
