These trees, by locals referred to as Queñua, Yagual and other names, can be found at altitudes of 4,500 m (14,760 ft) above sea level. Development of an incipient Paleogene topography between the present-day Andean plateau (Puna) and the Eastern Cordillera, southern Central Andes, NW Argentina Article Sep 2020 For decades, Chile claimed ownership of land on the eastern side of the Andes. The subsequent breakup of Pangaea and of its southern portion, Gondwana, dispersed these plates outward, where they began to take the form and position of the present-day continents. In: Spektrum der Wissenschaft 9/86: 42–54. It is the most extensive area of high plateau on Earth outside Tibet.The bulk of the Altiplano lies in Bolivia, but its northern parts lie in Peru, and its southern parts lie in Chile and Argentina. The western rim of the South American Plate has been the place of several pre-Andean orogenies since at least the late Proterozoic and early Paleozoic, when several terranes and microcontinents collided and amalgamated with the ancient cratons of eastern South America, by then the South American part of Gondwana. It is an elongate region of subdued relief, ∼1.2 × 10 5 km 2 and ∼4 km above sea level, bounded by the Eastern Cordillera and volcanic arc (Western Cordillera). This subduction-uplift process was accompanied by the intrusion of considerable quantities of magma from the mantle, first in the form of a volcanic arc along the western edge of the South American Plate and later by the injection of hot solutions into surrounding continental rocks; the latter process created numerous dikes and veins containing concentrations of economically valuable minerals that later were to play a critical role in the human occupation of the Andes. Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani and Young, editors (2008). ), 735–738. Other metals including iron, gold, and tin in addition to non-metallic resources are important. In the central Andes (∼15°S to ∼27°S), the Central Andean Plateau (the Altiplano-Puna Plateau) is characterized by a high-elevation (>3 km), low-relief interior plateau, surrounded by the higher, more rugged Western and Eastern Cordilleras, the Sierra Pampeanas, and the Santa Barbara Ranges (Fig. Parts of the La Paz conurbation, including the city of El Alto, extend up to 4,200 m (13,780 ft). Professor Emeritus of Geography, University of Wisconsin, Madison. Agent: MARCHANDS DES AMERIQUES INC. The climate is known to change drastically in rather short distances. Rainforests exist just kilometres away from the snow-covered peak Cotopaxi. The Andes Mountains host large ore and salt deposits and some of their eastern fold and thrust belt acts as traps for commercially exploitable amounts of hydrocarbons. The Andes extend from north to south through seven South American countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina. The Andean volcanism is a result of subduction of the Nazca Plate and Antarctic Plate underneath the South American Plate. Kuhle, M.

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. It is the result of a convergent plate boundary between the Nazca Plate and the South American Plate. The main surviving languages of the Andean peoples are those of the Quechua and Aymara language families.

Also, by early sowing, maize can be cultivated higher up in the mountains (up to 3,800 m (12,500 ft)). It is the result of a convergent plate boundary between the Nazca Plate and … Other important crops that originated from the Andes are tobacco and potatoes. The accepted time period for their rise had been from about 15 million to 6 million years ago.

The collision (or convergence) of two of these plates—the continental South American Plate and the oceanic Nazca Plate—gave rise to the orogenic (mountain-building) activity that produced the Andes. The mountains have a large effect on the temperatures of nearby areas. Potosí in present-day Bolivia and Cerro de Pasco in Peru was one of the principal mines of the Spanish Empire in the New World. The range is 7,000 km (4,350 mi) long, 200 to 700 km (124 to 435 mi) wide (widest between 18°S - 20°S latitude), and has an average height of about 4,000 m (13,123 ft).

The history of the Puna Plateau and its marginal basins and ranges in the Eastern Cordillera and the northern Sierras Pampeanas structural provinces in northwestern Argentina impressively documents the effects of tectonics and topography on atmospheric circulation patterns, the successive evolution of orographic barriers, as well as their influence on erosion and sedimentation processes. [13] Further south in southern Patagonia the onset of the Andean orogeny caused the Magallanes Basin to evolve from being an extensional back-arc basin in the Mesozoic to being a compressional foreland basin in the Cenozoic.[14]. Regardless, in modern times the clearance has accelerated, and the trees are now considered to be highly endangered, with some believing that as little as 10% of the original woodland remains.

The Andes rose to fame for their mineral wealth during the Spanish conquest of South America. The Southern and Central Andes and Patagonia. The Andes are the result of tectonic plate processes, caused by the subduction of oceanic crust beneath the South American Plate. The Incas formed this civilization through imperialistic militarism as well as careful and meticulous governmental management. In the rainy season (summer), part of the rangeland is used for cropping (mainly potatoes, barley, broad beans and wheat). [30][31] The Andean condor, the largest bird of its kind in the Western Hemisphere, occurs throughout much of the Andes but generally in very low densities. Huancas, Chachapoyas, Cañaris) and a small army of 180 Spaniards led by Francisco Pizarro. In unirrigated land, pasture is the most common type of land use. The intensity of this activity increased during the Cenozoic Era, and the present shape of the cordilleras emerged. It was sundown and the local vendors were no longer there. Approximately 170 million years ago this complex geologic matrix began to be uplifted as the eastern edge of the Nazca Plate was forced under the western edge of the South American Plate (i.e., the Nazca Plate was subducted), the result of the latter plate’s westward movement in response to the opening of the Atlantic Ocean to the east.
