It is over 7,000 km (4,400 miles) long, 500 km (300 miles) wide in some parts (widest between 18° to 20°S latitude), and of an average height of about 4,000 m (13,000 ft).

The Andean range is composed principally of two great ranges, the Cordillera Oriental and the Cordillera Occidental, often separated by a deep intermediate depression, in which arise other chains of minor importance, the chief of which is Chile's Cordillera de la Costa. Other small chains arise on the sides of the great chains. The Cordillera de la Costa starts from the southern extremity of the continent and runs in a northerly direction, parallel with the coast, being broken up at its beginning into a number of islands and afterwards forming the western boundary of the great central valley of Chile. To the north this coastal chain continues in small ridges or isolated hills along the Pacific Ocean as far as Venezuela, always leaving the same valley more or less visible to the west of the western great chain. The mountains extend over seven countries: Argentina, Bolivia, Chile, Colombia, Ecuador, Peru and Venezuela, some of which are known as Andean States. One theory says the name Andes comes from the Quechua word anti, which means "high crest". Another theory says that the name Andes derived from the Spanish word "andén" which means terrace in reference to the cultivation terraces used by the Incas and other related peoples.

Rift valley near Quilotoa, Ecuador.

The Andes fundamentally are the result of plate tectonics processes, caused by the subduction of the Nazca plate beneath the South American plate. The boundary between the two plates is marked by the Peru-Chile oceanic trench. The descending Nazca plate is young and buoyant lithosphere, which resists subduction, causing a lot of earthquakes. The formation of the Andes began in the Jurassic period. 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. Tectonic forces along the subduction zone along the entire west coast of South America where the Nazca Plate and a part of the Antarctic Plate are sliding beneath the South American Plate continue to produce an ongoing orogenic event resulting in minor to major earthquakes and volcanic eruptions to this day. In the extreme south a major transform fault separates Tierra del Fuego from the small Scotia Plate. Across the 1,000 km wide Drake Passage lie the mountains of the Antarctic Peninsula south of the Scotia Plate which appear to be a continuation of the Andes chain.

The Andes range has many active volcanoes, including Cotopaxi, one of the highest active volcanoes in the world. Cotopaxi is a volcano located about 50 km south of Quito, Ecuador. ...


The Andes can be divided into three sections: the Southern Andes in Argentina and Chile; the Central Andes, including the Chilean and Peruvian cordilleras; and the northern section in Venezuela, Colombia, and northern Ecuador consisting of two parallel ranges, the Cordillera Occidental and the Cordillera Oriental. In Colombia, north to the border with Ecuador, the Andes split in three parallel ranges, western, central and eastern. (cordillera occidental, central y oriental). The eastern range is the only that extends to Venezuela. The term cordillera comes from the Spanish word meaning 'rope'. The Andes range is approximately 200–300 km wide throughout its length, except in the Bolivian flexure where it is 640 km wide. The islands of Aruba, Bonaire, and Curaçao, which lie in the Caribbean Sea off the coast of Venezuela, represent the submerged peaks of the extreme northern edge of the Andes range.

[edit] Climate

The climate in the Andes varies greatly depending on location, altitude, and proximity to the sea. The southern section is rainy and cool, the central Andes are dry. The northern Andes are typically rainy and warm, with an average temperature of 18 °C in Colombia. The climate is known to change drastically. Tropical rainforests exist just miles away from the snow covered peak, Cotopaxi. The mountains have a large effect on the temperatures of nearby areas. The snow line depends on the location. It is at between 4,500–4,800 m in the tropical Ecuadorian, Colombian, Venezuelan, and northern Peruvian Andes, rising to 4,800–5,200 m in the drier mountains of southern Peru south to northern Chile south to about 30°S, then descending to 4,500 m on Aconcagua at 32°S, 2,000 m at 40°S, 500 m at 50°S, and only 300 m in Tierra del Fuego at 55°S; from 50°S, several of the larger glaciers descend to sea level (Google Earth/World Wind images).

[edit] Plant and animal life

Tropical rainforests and rainforests encircle the northern Andes. The cinchona, a source of quinine which is used to treat malaria, is found in the Bolivian Andes. The high-altitude Polylepis forests are present in the Andean areas of Ecuador, Peru and Bolivia. The trees, Queñua, Yagual and other names that local people use to call them, can be found at altitudes of 4,500 m above sea level. Once abundant, the forests began disappearing during the Incan period when much of it was used for building material and cooking fuel. The trees are now considered to be highly endangered with only 10% of the original forests remaining [1]. Tropical and subtropical moist broadleaf forests, also known as tropical rain forests, are a tropical and subtropical biome. ... A rainforest is a forested biome with high annual rainfall. ...

The llama can be found living at high altitudes, predominantly in the Peru and Bolivia. The alpaca, a type of llama, is raised for its wool. The nocturnal chinchilla, an endangered member of the rodent order, inhabits the Andes' alpine regions. The South American condor is the largest bird of its kind in the Western hemisphere. Other animals include the huemul, cougar, camelids and, for birds, the partridge, parina, huallata, and coot. Llamas and cougars play important roles in many Andean cultures.

The Inca Empire developed in the northern Andes during the 1400s. The Incas formed this civilization through careful and meticulous governmental management. The government sponsored the construction of aqueducts and roads, some of which, like those created by the Romans, are still in existence today. The aqueducts turned the previously scattered Incan tribe into the agricultural and eventually militaristic masters of the region.

Devastated by deadly European diseases to which they had no immunity, the Incas were conquered by an army of 180 men led by Pizarro in 1532. One of the few Inca cities the Spanish never found in their conquest was Machu Picchu, which lay hidden on a peak on the edge of the Andes where they descend to the Amazon. The main surviving languages of the Andean peoples are those of the Quechua and Aymara language families. Immunity is a medical term that describes a state of having sufficient biological defenses to avoid infection, disease, or other unwanted biological invasion. ...

[edit] Transportation

The people of the Andes are not well connected to urban regions. Due to the arduous terrain, vehicles are of little use. People generally walk to their destinations, using the llama as their primary pack animal.


[edit] Agriculture

The ancient peoples of the Andes such as the Incas have practiced irrigation techniques for over 6,000 years. Because of the mountain slopes, terracing has been a common practice. Maize was an important crop for these people. Currently, tobacco, cotton and coffee are the main export crops. The potato holds a very important role as an internally consumed crop.
