Andes

The Andes or Andean Mountains are the longest continental mountain range in the world. They form a continuous highland along the western edge of South America. This range is about 7000km long, about 200to wide, and of an average height of about 4000m. The Andes extend from north to south through seven South American countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Argentina and Chile.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.
