Andes - Santiago - Chile by SGastaldi on Flickr.
The Andes are the world’s longest continental mountain range. It is a continuous chain of highland along the western coast of South America. The range is over 7,000 km (4,300 mi) long, 200 km (120 mi) to 700 km (430 mi) wide (widest between 18° to 20°S latitude), and of an average height of about 4,000 m (13,000 ft).
Over its length the Andean range is at several locations split into several ranges, often two great ranges, named Cordillera Oriental and the Cordillera Occidental, often separated by an intermediate depression. The Andes mountains extend over seven countries: Argentina, Bolivia, Chile, Colombia, Ecuador, Peru, and Venezuela, some of which are known as Andean States.
The Andes mountain range is the highest mountain range outside Asia. The highest peak, Aconcagua, rises to 6,962 m (22,841 ft) above sea level.
