Chile
The Chilean relief consists of the central depression, which crosses the country longitudinally, flanked by two mountain ranges that make up about 80% of the territory: the Andes mountains to the east-natural border with Bolivia and Argentina in the region of Atacama and the Coastal Range west-minor height from the Andes. Chile's highest peak is the Nevado Ojos del Salado, at 6891.3 m, which is also the highest volcano in the world. The highest point of the Coastal Range is Vicuña Mackenna, at 3114 meters, located in the Sierra Vicuña Mackenna, the south of Antofagasta. Among the coastal mountains and the Pacific is a series of coastal plains, of variable length, which allow the settlement of coastal towns and big ports. Some areas of the plains territories encompass territory east of the Andes, and the Patagonian steppes and Magellan, or are high plateaus surrounded by high mountain ranges, such as the Altiplano or Puna de Atacama.
Mountain range
Most geologically young mountain ranges on the Earth's land surface are associated with either the Pacific Ring of Fire or the Alpide Belt. The Pacific Ring of Fire includes the Andes of South America, extends through the North American Cordillera along the Pacific Coast, the Aleutian Range, on through Kamchatka, Japan, Taiwan, the Philippines, Papua New Guinea, to New Zealand. The Andes is long and is often considered the world's longest mountain system.
