The primary range of mountains on the western coast of South America is the Andes. Stretching over 7,000 kilometers (4,300 miles) through seven countries, the Andes is the longest continental mountain range in the world. It is known for its diverse ecosystems, rich mineral resources, and significant cultural heritage, including many indigenous communities. The Andes support various climates and are home to notable peaks, such as Mount Aconcagua, which is the highest peak in South America.
