The Andes (/ˈ æ n d iː z / AN -deez), Andes Mountains or Andes Range (Spanish: Cordillera de los Andes; Quechua: Anti) is the longest continental mountain range in the world, forming a continuous plateau towards the west. The boundaries of South America. It is 8,900 km (5,530 mi) long, 200–700 km (124–435 mi) wide (at its widest between 18°S–20°S), and has an average elevation of about 4,000 m (13,123 ft). The Andes stretch from north to south through seven countries in South America: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile and Argentina.

At the same time, the Andes were divided into several belts, which were separated by a central depression. The Andes are home to several high plateaus – some of which are home to major cities such as Quito, Bogota, Cali, Arequipa, Medellin, Bucaramanga, Sucre, Mérida, El Alto and La Paz. The Altiplano is the second highest plateau in the world after the Tibetan Plateau. These regions are divided into three main parts based on climate: the tropical highlands, the dry Andes, and the wet Andes.

The Andes are the highest mountain range outside of Asia. The highest mountain outside of Asia, Aconcagua Argentina rises to 6,961 m (22,838 ft) above sea level. The peak of Chimborazo in the Ecuadorian Andes is farther from the Earth’s surface than anywhere else in the world due to the contraction of the equator caused by the Earth’s rotation. The highest volcanoes in the world are in the Andes, including Ojos del Salado on the border of Chile and Argentina, which rises to 6,893 m (22,615 ft).

The Andes are also part of the American Cordillera, a series of mountains (cordillera) consisting of almost continuous mountain ranges that form the “spine” of Western America and Antarctica.

The etymology of the word Andes is controversial. The majority opinion is that it is derived from the Quechua word for “east”.

And is used as a descriptive name for some adjacent parts of the Andes, as well as the Andes and the combined mountain range in the western part of the Americas.

The Leeward Antilles of Aruba, Bonaire, and Curaçao, located in the Caribbean Sea off the coast of Vesuela, were previously thought to restore the submerged point of the northern edge of the Andes, but ongoing geological studies show that such simplicity is false. Complex tectonic boundaries between plates. South America and the Caribbean are not fair.

The Andes are a Mesozoic and Tertiary orogenic belt of mountains along the Pacific Ring of Fire, an area of ​​volcanic activity that spans both the Americas Pacific Rim and the Asia Pacific region. The Andes are the result of a plate tectonic process caused by the subduction of the oceanic crust from the South American plate to the Nazca plate and the South American plate. These processes are accelerated by the climate. As the rising Andes create a rain shadow on the west coast of Chile, the currents The sea and strong winds take the moisture away from the coast of Chile. This has starved some parts of the subterranean area, resulting in excessive attraction and rates of Raise the coast to increase.

The main reason for the rise of the Andes is the compression of the western edge of the South American plate due to the subduction of the Nazca plate and the Antarctic plate. To the east, the Andes are bounded by several sedimentary basins, such as the Orinoco, Amazon Basin, Madre de Dios, and Gran Chaco, which separate the Andes from the ancient cratons of South America. To the south, the Andes form a long border with the former Patagonia Terrane. In the west, the Andes and the Pacific Ocean, even the Peruvian-Chilean Trichy may be considered their western limit. Geographically, the Andes define their western border with the presence of coastal plains and rugged terrain. The Andes also contain large amounts of iron ore, which is found in many mountainous areas.

Andean mountains have a series of bds or oroclines. Bolivian Orocline is a region located along the coast of South America and the Andes Mountains at about 18 degrees latitude.

At this point, the direction of the Andes runs from the northwest of Peru to the south in Chile and Argentina.

The northern and southern Andean parts of the Orocline rotate 15° to 20° counterclockwise and clockwise, respectively.

The Bolivian Orocline overlaps the area of ​​maximum width of the Altiplano Plateau, and according to Isaacs (1988) the Orocline is related to crustal shortening.

Further south of the Maipo Orocline is a gentle orocline between 30°S and 38°S, with a concave seaward break to the trd at 33°S.

The western margin of the South American plate is home to several ancient pre-Andean tectonics of at least the late Proterozoic and early Paleozoic, where several terranes and microcontinents collided and merged with the ancient cratons of eastern South America. Part of Gondwana.

The formation of the modern Andes began in the Triassic when Pangea began to break apart, causing many rifts. Development continued during the Jurassic period as well. It was during the Cretaceous period that the Andes assumed their Persian form due to the uplift, faulting and folding of the sedimentary and metamorphic rocks of the ancient cratons to the east. The rise of the Andes is not constant, as the regions have experienced varying degrees of tectonic stress, uplift, and erosion.

Tectonic forces above the subduction zone on the west coast of South America, where the Nazca plate and part of the Antarctic plate are moving through the South American plate, cause continuous orogenic subduction that results in small to large earthquakes and volcanic eruptions. Today in the southernmost part, a large transform fault separates Tierra del Fuego from the small Scottish plate. Crossing 1,000 kilometers (620 miles) of the Drake Passage are the mountains of the Antarctic Peninsula south of the Scotian Plate, a continuation of the Andes chain.

The region far east of the Andes is subject to many changes caused by the Andean orogeny. Part of the Sunsás Orog has disappeared from the face of the Andes-dominated Amazon Craton.

The Sierras de Córdoba, where the influence of the ancient Pampa orogeny can be observed, owes its modern height and brightness to the tertiary orogenies of the Andes.

Further south in southern Patagonia, the onset of the Andean orogeny led to the evolution of the Magellan Basin from a Mesozoic back-arc basin to a Cozoic thrust basin.

There are several active volcanoes in the Andes, which are spread across four volcanic zones separated by inactive zones. Andean volcanoes are the result of the subduction of the Nazca plate and the Antarctic plate under the South American plate. The belt is divided into four main volcanic zones, which are separated from each other by volcanic gaps. Belt volcanoes differ in the style of activity, products and morphology.

Although some of the variation can be explained by the volcanic zone to which the volcano belongs, there are significant differences within volcanic zones and between neighboring volcanoes. The Andean volcanic belt, although a common site of calcareous and subduction volcanism, has a wide variety of volcanotectonics, such as rift systems and extension zones, transpressional faults, subduction of mid-ocean ridges, and submarine chains. A wide range of crustal thicknesses and magma paths and different amounts of crustal absorption.

The Andes Mountains contain large amounts of ore and salt, and parts of the continental shelf and their belts act as traps for commercially exploitable hydrocarbons. The countries of the Atacama desert produce some of the largest deposits of porphyry copper, making Chile and Peru the world’s first and second largest exporters of copper. Porphyry copper on the western slopes of the Andes flows from hydrothermal fluids (mostly water) when plutons or volcanic systems cool. Porphyry minerals are more suitable
