The Andes mountain range as seen from a plane, between Santiago de Chile and Mendoza, Argentina, in summer. The large icefield corresponds to the southern slope of San José volcano (left) and Marmolejo (right). Tupungato at their right.
The Andes Mountains are the world's highest mountain range outside Asia. The highest mountain outside Asia, Argentina's Mount Aconcagua, rises to an elevation of about 6,961 m (22,838 ft) above sea level. The peak of Chimborazo in the Ecuadorian Andes is farther from the Earth's center than any other location on the Earth's surface, due to the equatorial bulge resulting from the 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).
The Andes are also part of the American Cordillera, a chain of mountain ranges (cordillera) that consists of an almost continuous sequence of mountain ranges that form the western "backbone" of North America, Central America, South America and Antarctica.
The etymology of the word Andes has been debated. The majority consensus is that it derives from the Quechua word anti, which means "east" as in Antisuyu (Quechua for "east region"), one of the four regions of the Inca Empire.
