Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani and Young, editors (2008). The Andean mountain system is the result of global plate-tectonic forces during the Cenozoic Era (roughly the past 65 million years) that built upon earlier geologic activity. The main surviving languages of the Andean peoples are those of the Quechua and Aymara language families. To the west, the Andes end at the Pacific Ocean, although the Peru-Chile trench can be considered their ultimate western limit. Coffre renforcé en argent ouvert: Objet fourni : Purian mûr: Description Les purians sont super bons, mais il vaut mieux les donner. (Eds. The etymology of the word Andes has been debated. The northern Andes are typically rainy and warm, with an average temperature of 18 Â°C (64 Â°F) in Colombia. The system—part of the larger circum-Pacific volcanic chain that often is called the Ring of Fire—remains volcanically active and is subject to devastating earthquakes. Because of the mountain slopes, terracing has been a common practice. Peru also contains the 4th largest goldmine in the world: the Yanacocha. Development in Quaternary Science, vol. Kuhle, M. (1990): The Probability of Proof in Geomorphology—an Example of the Application of Information Theory to a New Kind of Glacigenic Morphological Type, the Ice-marginal Ramp (Bortensander). The climate is known to change drastically in rather short distances. Greater Buenos Aires is home to about one-third of the Argentine people. [5] The specific point at 18° S where the coastline bends is known as the "Arica Elbow". Haut plateau des Andes en 4 lettres. It lies in west-central South America, where the Andes are at their widest, is the most extensive area of high plateau on Earth outside of Tibet. Other metals including iron, gold, and tin in addition to non-metallic resources are important. The Andes are the location of several high plateaus—some of which host major cities such as Quito, Bogotá, Cali, Arequipa, Medellín, Bucaramanga, Sucre, Mérida and La Paz. About 30,000 species of vascular plants live in the Andes, with roughly half being endemic to the region, surpassing the diversity of any other hotspot. Only recently the ends of some highways that came rather close to one another from the east and the west have been connected.

In the extreme south, a major transform fault separates Tierra del Fuego from the small Scotia Plate. Along their length, the Andes are split into several ranges, separated by intermediate depressions. Let us know if you have suggestions to improve this article (requires login). The Andes are a Mesozoic–Tertiary orogenic belt of mountains along the Pacific Ring of Fire, a zone of volcanic activity that encompasses the Pacific rim of the Americas as well as the Asia-Pacific region. The volcanoes of the belt are diverse in terms of activity style, products and morphology. Syrah Chile $27.95 (16795) 89; Score: 89 pts Reviews: 3. Bolivia has been a completely landlocked country ever since. 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. 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. Located on a high-altitude plateau at the edge of the Andes Mountains, the province is responsible for roughly 70 percent of the country's annual wine production. Part III: South America, Asia, Africa, Australia, Antarctica. ), 735–738. At glacial times, however, c. 20,000 years ago, the glaciers were over ten times longer.

There is no universal agreement about the major north-south subdivisions of the Andes system. [16], Though precipitation increases with the height, there are semiarid conditions in the nearly 7,000-metre (22,966 ft) highest mountains of the Andes. The directional trend of both the cordilleras generally is north-south, but in several places the Cordillera Oriental bulges eastward to form either isolated peninsula-like ranges or such high intermontane plateau regions as the Altiplano (Spanish: “High Plateau”), occupying adjoining parts of Argentina, Chile, Bolivia, and Peru. The southern section is rainy and cool, the central section is dry. However, through the use of more advanced techniques, researchers in the early 21st century were able to determine that the uplift started much earlier, about 25 million years ago. It was during the Cretaceous Period that the Andes began to take their present form, by the uplifting, faulting and folding of sedimentary and metamorphic rocks of the ancient cratons to the east. Development in Quaternary Science, Vol. [33] A few species of hummingbirds, notably some hillstars, can be seen at altitudes above 4,000 m (13,100 ft), but far higher diversities can be found at lower altitudes, especially in the humid Andean forests ("cloud forests") growing on slopes in Colombia, Ecuador, Peru, Bolivia and far northwestern Argentina. It remains unclear if the patchy distribution of these forests and woodlands is natural, or the result of clearing which began during the Incan period. Huancas, Chachapoyas, Cañaris) and a small army of 180 Spaniards led by Francisco Pizarro. la surface plane du plateau original finit par disparaître et seules les montagnes subsistent. (1929): Zur Glazialgeologie der chilenischen Anden. Irrigation is helpful in advancing the sowing data of the summer crops which guarantees an early yield in the period of food shortage. 2c. For the purposes of this discussion, the system is divided into three broad categories. However, there is one railroad that connects Chile with Peru via the Andes, and there are others that make the same connection via southern Bolivia. It is the result of a convergent plate boundary between the Nazca Plate and … Andes Plateau, 700, Chile, 2012. Release: October 31, 2020. Cities and large towns are connected with asphalt-paved roads, while smaller towns are often connected by dirt roads, which may require a four-wheel-drive vehicle.[35].

Best trails in Réserve naturelle du plateau des Landes. The main cause of the rise of the Andes is the compression of the western rim of the South American Plate due to the subduction of the Nazca Plate and the Antarctic Plate. Définition ou synonyme. ): Alluvial fans: A field approach. (Elsevier B.V., Amsterdam). [6] The Andean segment north and south of the Orocline have been rotated 15° to 20° counter clockwise and clockwise respectively. La plus douce des offrandes. The rise of the Andes has not been constant, as different regions have had different degrees of tectonic stress, uplift, and erosion. This dry steppe climate is considered to be typical of the subtropical position at 32–34° S. The valley bottoms have no woods, just dwarf scrub. [32] Other animals found in the relatively open habitats of the high Andes include the huemul, cougar, foxes in the genus Pseudalopex,[30][31] and, for birds, certain species of tinamous (notably members of the genus Nothoprocta), Andean goose, giant coot, flamingos (mainly associated with hypersaline lakes), lesser rhea, Andean flicker, diademed sandpiper-plover, miners, sierra-finches and diuca-finches. 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 accepted time period for their rise had been from about 15 million to 6 million years ago. [28], The vicuña and guanaco can be found living in the Altiplano, while the closely related domesticated llama and alpaca are widely kept by locals as pack animals and for their meat and wool. Devastated by European diseases to which they had no immunity and civil wars, the Incas were defeated in 1532 by an alliance composed of tens of thousands of allies from nations they had subjugated (e.g. The Andes can be divided into three sections: The Leeward Antilles islands Aruba, Bonaire, and Curaçao, which lie in the Caribbean Sea off the coast of Venezuela, were formerly thought to represent the submerged peaks of the extreme northern edge of the Andes range, but ongoing geological studies indicate that such a simplification does not do justice to the complex tectonic boundary between the South American and Caribbean plates. [30], Birds of humid Andean forests include mountain-toucans, quetzals and the Andean cock-of-the-rock, while mixed species flocks dominated by tanagers and furnariids commonly are seen – in contrast to several vocal but typically cryptic species of wrens, tapaculos and antpittas. 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 1; Allmendinger et al., 1997; Isacks, 1988; Strecker et al., 2007).

The Andes range has many active volcanoes distributed in four volcanic zones separated by areas of inactivity. Abstract. 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). below the Altiplano. Because of the tortuous terrain in places, villages and towns in the mountains—to which travel via motorized vehicles is of little use—are still located in the high Andes of Chile, Bolivia, Peru, and Ecuador. Terracing, however, was only extensively employed after Incan imperial expansions to fuel their expanding realm. [32], Lake Titicaca hosts several endemics, among them the highly endangered Titicaca flightless grebe[32] and Titicaca water frog. (eds. In the south, the Andes share a long boundary with the former Patagonia Terrane. [32] These forest-types, which includes the Yungas and parts of the Chocó, are very rich in flora and fauna, although few large mammals exist, exceptions being the threatened mountain tapir, spectacled bear and yellow-tailed woolly monkey. In: Zentralblatt für Geologie und Paläontologie Teil 1 11/12, Verhandlungsblatt des Südamerika-Symposiums 1984 in Bamberg: 1635–1646. 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. [11], The regions immediately east of the Andes experience a series of changes resulting from the Andean orogeny. [6][7] The Bolivian Orocline area overlaps with the area of maximum width of the Altiplano Plateau and according to Isacks (1988) the Orocline is related to crustal shortening. The Andes are the result of tectonic plate processes, caused by the subduction of oceanic crust beneath the South American Plate. Currently, tobacco, cotton and coffee are the main export crops. ; Hughes, P.D. In the high Andes of central Chile and Mendoza Province, rock glaciers are larger and more common than glaciers; this is due to the high exposure to solar radiation. [29], The Andes are rich in fauna: With almost 1,000 species, of which roughly 2/3 are endemic to the region, the Andes are the most important region in the world for amphibians. Mirador de los Andes (Andes Lookout) was without trees, the air was thin and it was very quiet. 224-225. In unirrigated land, pasture is the most common type of land use. 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. To the east, the Andes range is bounded by several sedimentary basins, such as Orinoco, Amazon Basin, Madre de Dios and Gran Chaco, that separate the Andes from the ancient cratons in eastern South America. In: GeoJournal 14 (4); Kluwer, Dordrecht/ Boston/ London: 393–421. 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. Agent: MARCHANDS DES AMERIQUES INC. Rainforests and tropical dry forests[27] used to encircle much of the northern Andes but are now greatly diminished, especially in the Chocó and inter-Andean valleys of Colombia.
