The Southern Andes in Argentina and Chile, south of Llullaillaco, The Central Andes in Peru and Bolivia, and The Northern Andes in Venezuela, Colombia, and Ecuador. At the northern end of the Andes, the separate Sierra Nevada de Santa Marta range is often, but not always, treated as part of the Northern Andes. [3]
Aucanquilcha is part of the Central Volcanic Zone (CVZ) of the Andes, a highly silicic volcanic zone in South America. The CVZ generates magmas at a rate of 0.11 cubic kilometres per millennium (0.026 cubic miles per millennium), one tenth of the global average of arc magma production, and lies about 135–180 kilometres (84–112 mi) above the Wadati–Benioff zone.
The rugged topography of the Central Andes creates the warm, dry valleys that typifies the valles. Generally lying between 1,200 and 3,500 meters above sea level (m.a.s.l.) or 4,000 - 13,000 feet above sea level. Much of the area features steep hillsides and deep canyons, including the world's deepest canyon, the Colca Canyon.
The earliest civilizations were on the hyper-arid desert coast of Peru. Agriculture was possible only with irrigation in valleys crossed by rivers coming from the high Andes, plus in a few fog oases called lomas. In the Andes, agriculture was limited by thin soils, cold climate, low or seasonal precipitation, and a scarcity of flat land.
Aconcagua (Spanish pronunciation: [akoŋˈkaɣwa]) is a mountain in the Principal Cordillera [4] of the Andes mountain range, in Mendoza Province, Argentina.It is the highest mountain in the Americas, the highest outside Asia, [5] and the highest in both the Western Hemisphere and the Southern Hemisphere [1] with a summit elevation of 6,961 metres (22,838 ft).
The Altiplano (Spanish for "high plain"), Collao (Quechua and Aymara: Qullaw, meaning "place of the Qulla") or Andean Plateau, in west-central South America, is the most extensive high plateau on Earth outside Tibet. The plateau is located at the latitude of the widest part of the north–south-trending Andes.
Mountain tapirs are also important seed dispersers in their environments, and have been identified as a keystone species of the high Andes. A relatively high proportion of plant seeds eaten by mountain tapirs successfully germinate in their dung , probably due to a relatively inefficient digestive system and a tendency to defecate near water.
The Andes, from a sub-tropical forest to snow-capped peaks in one scene. The chain of mountains called the Andes, comprising 28 percent of the national territory, runs the length of Peru, a narrow 80 km (50 miles) wide at the Ecuadorian border in the north and 350 km (220 miles) wide in the south along the border with Bolivia. The Andes, with ...
