They form a continuous highland along the western edge of South America . This range is about 7,000 km (4,300 mi) long, about 200 to 700 km (120 to 430 mi) wide (widest between 18 ° south and 20 ° south latitude), and of an average height of about 4,000 m (13,000 ft). The Andes extend from north to south through seven South American countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Argentina and Chile . </P> <P> Along their length, the Andes are split into several ranges, which are separated by intermediate depressions . The Andes are the location of several high plateaus--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 after 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 . </P>
