The Andes is the longest continental mountain range in the world. It is a continual range of highlands along the western coast of South America. This range is about long, about to wide (widest between 18° south and 20° south latitude), and of an average height of about . The Andes extend from north to south through seven South American countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina. Along its length, the Andes is split into several ranges, which are separated by intermediate depressions. The Andes is the location of several high plateaux – some of which host major cities such as Quito, Bogotá, Arequipa, Medellín, Sucre, Mérida, and La Paz. The Altiplano plateau is the world’s second-highest following the Tibetan plateau. These ranges are in turn grouped into three major divisions based on climate: the Tropical Andes, the Dry Andes, and the Wet Andes. The Andes is the world’s highest mountain range outside of Asia. The highest peak, Mount Aconcagua, rises to an elevation of about above sea level. The peak of Chimborazo in the Ecuadorean Andes is farther from Earth’s center than any other location on Earth’s surface, due to the equatorial bulge resulting from Earth’s rotation. The world’s highest volcanoes are in the Andes, including Ojos del Salado on the Chile-Argentina border which rises to 6,893 m (22,615 ft).
