The Andes, Andes Mountains or Andean Mountains are the longest continental mountain range in the world, forming a continuous highland along the western edge of South America. The range is 6,999 km (4,349 mi) long, 200 to 700 km wide, and has an average height of about 4,000 m (13,123 ft). The Andes extend from north to south through seven South American countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina.
Chile, officially the Republic of Chile, is a country in the western part of South America. It is the southernmost country in the world, and the closest to Antarctica; occupying a long and narrow strip of land between the Andes to the east and the Pacific Ocean to the west. Chile covers an area of 756,096 square kilometers (291,930 sq mi), with a population of 17.5 million as of 2017. It shares land borders with Peru to the north, Bolivia to the north-east, Argentina to the east, and the Drake Passage in the far south. Chile also controls the Pacific islands of Juan Fernández, Isla Salas y Gómez, Desventuradas, and Easter Island in Oceania. It also claims about 1,250,000 square kilometers (480,000 sq mi) of Antarctica under the Chilean Antarctic Territory. The country's capital and largest city is Santiago, and its national language is Spanish.
Chili peppers, from Nahuatl chīlli, are varieties of the berry-fruit of plants from the genus Capsicum, which are members of the nightshade family Solanaceae, cultivated for their pungency. Chili peppers are widely used in many cuisines as a spice to add "heat" to dishes. Capsaicin and related compounds known as capsaicinoids are the substances giving chili peppers their intensity when ingested or applied topically. Other varieties of capsicum include bell peppers, but while chili peppers are pungent or "spicy", bell peppers are generally not and provide additional sweetness and flavor to a meal rather than “heat.”
A hacienda, in the colonies of the Spanish Empire, is an estate, similar to a Roman latifundium. Some haciendas were plantations, mines or factories. Many haciendas combined these activities. The word is derived from the Spanish verb "hacer" or its gerund "haciendo", from Latin "facere", meaning 'to make' and 'making' respectively, and were largely business enterprises consisting of various money-making ventures including raising farm animals and maintaining orchards.
Nothofagus, also known as the southern beeches, is a genus of 43 species of trees and shrubs native to the Southern Hemisphere in southern South America and Australasia. The species are ecological dominants in many temperate forests in these regions. Some species are reportedly naturalised in Germany and Great Britain. The genus has a rich fossil record of leaves, cupules, and pollen, with fossils extending into the late Cretaceous period and occurring in Australia, New Zealand, Antarctica, and South America.
The Valdivian temperate forests (NT0404) is an ecoregion on the west coast of southern South America, in Chile and extending into Argentina. It is part of the Neotropical realm. The forests are named after the city of Valdivia. The Valdivian temperate rainforests are characterized by their dense understories of bamboos, ferns, and for being mostly dominated by evergreen angiosperm trees with some deciduous specimens, though conifer trees are also common.
Alstroemeriaceae is a family of flowering plants, with 254 known species in four genera, almost entirely native to the Americas, from Central America to southern South America. One species of Luzuriaga occurs in New Zealand, and the genus Drymophila is endemic to south-eastern Australia.
The Humboldt Current, also called the Peru Current, is a cold, low-salinity ocean current that flows north along the western coast of South America. It is an eastern boundary current flowing in the direction of the equator, and extends 500–1,000 km (310–620 mi) offshore. The Humboldt Current is named after the German naturalist Alexander von Humboldt even though it was discovered by José de Acosta 250 years before Humboldt. In 1846, von Humboldt reported measurements of the cold-water current in his book Cosmos.
The kodkod, also called güiña, is the smallest felid species native to the Americas. It lives primarily in central and southern Chile, as well as marginally in adjoining areas of Argentina. Its area of distribution is small compared to the other South American cats. Since 2002, it has been listed as Vulnerable on the IUCN Red List as the total population may comprise less than 10,000 mature individuals; it is threatened due to persecution, and loss of habitat and prey base.
Anapidae is a family of rather small spiders with 231 described species in 58 genera. It includes the former family Micropholcommatidae as the subfamily Micropholcommatinae, and the former family Holarchaeidae. Most species are less than 2 millimetres (0.079 in) long.
The Central Valley, Intermediate Depression, or Longitudinal Valley is the depression between the Chilean Coastal Range and the Andes Mountains. The Chilean Central Valley extends from the border with Peru to Puerto Montt in southern Chile, with a notable interruption at Norte Chico. South of Puerto Montt the valley has a continuation as a series of marine basins up to the isthmus of Ofqui. Some of Chile's most populous cities lie within the valley including Santiago, Temuco, Rancagua, Talca and Chillán.
The Andean Volcanic Belt is a major volcanic belt along the Andean cordillera in Argentina, Bolivia, Chile, Colombia, Ecuador, and Peru. It is formed as a result of subduction of the Nazca Plate and Antarctic Plate underneath the South American Plate. The belt is subdivided into four main volcanic zones which are separated by volcanic gaps. The volcanoes of the belt are diverse in terms of activity style, products, and morphology. While some differences can be explained by which volcanic zone a volcano belongs to, there are significant differences within volcanic zones and even between neighboring volcanoes. Despite being a type location for calc-alkalic and subduction volcanism, the Andean Volcanic Belt has a broad range of volcano-tectonic settings, as it has rift systems and extensional zones, transpressional faults, subduction of mid-ocean ridges and seamount chains as well as a large range of crustal thicknesses and magma ascent paths and different amounts of crustal assimilations.
The Mutisioideae are a subfamily in the plant family Asteraceae that includes about 630 species assigned to 44 different genera. This subfamily is mainly native in South America, except for Adenocaulon, Chaptalia, Gerbera, Trichocline, which have species in all continents other than Europe and Antarctica. Common characters are the deeply incised corollas of the disc florets, with five lobes, sometimes merged in two lips, flower heads with overlapping involucral bracts, anthers with tails and pointy tips, the styles usually stick far out of the florets and are essentially hairless. Most species are herbs, but some are vines, shrubs, or small trees.
Nassauvia is a genus of flowering plants in the tribe Nassauvieae within the family Asteraceae. It is native to Argentina, Bolivia, Chile and the Falkland Islands.
The Atacama Desert is a desert plateau in South America covering a 1,600 km (990 mi) strip of land on the Pacific coast, west of the Andes Mountains. The Atacama Desert is the driest nonpolar desert in the world, as well as the only true desert to receive less precipitation than the polar deserts and the largest fog desert in the world. Both regions have been used as experimentation sites on Earth for Mars expedition simulations. The Atacama Desert occupies 105,000 km2 (41,000 sq mi), or 128,000 km2 (49,000 sq mi) if the barren lower slopes of the Andes are included. Most of the desert is composed of stony terrain, salt lakes (salares), sand, and felsic lava that flows towards the Andes.
Kunturiri is a volcano in the Andes on the border of Bolivia and Chile which rises up to 5,762 metres (18,904 ft). On the Chilean side it is located in the Arica and Parinacota Region and on the Bolivian side in the Oruro Department, Sajama Province, Curahuara de Carangas Municipality, Sajama Canton as well as in the La Paz Department, Pacajes Province, Calacoto Municipality, Ulloma Canton.
The Nassauvieae are a tribe of flowering plants in the family Asteraceae.
Abanico Formation is a 3 kilometres (9,800 ft) thick sedimentary formation exposed in the Andes of Central Chile. The formation has been deposited in a timespan from the Eocene to the Miocene. Abanico Formation's contact with the overlying Miocene Farellones Formation has been the subject of differing interpretations since the 1960s. A small part of the formation crops out in the Mendoza Province of western Argentina.
Ranquil Formation is a Miocene and Pliocene sedimentary formation located in Arauco Province in south–central Chile, including outcrops in Mocha Island. The formation has its greatest thicknesses in the south-west, where its sediments were largely deposited in marine conditions. It overlies unconformably sedimentary formations of the Paleocene-Eocene Lebu Group. The formation is part of the fill of Arauco Basin which is a sedimentary basin that extends south of Concepción.
Caldera Basin is a sedimentary basin located in the coast of northern Chile west of Copiapó. The basin has a fill of marine sediments of Late Cenozoic age. With a north-south extension of 43 kilometres (27 mi) and an east-west width of 20 kilometres (12 mi) the basin occupies an area between the coast and the Chilean Coast Range and between the port of Caldera and the mouth of Copiapó River. The sedimentary fill rests on metamorphic rocks of Paleozoic age and on plutonic rocks of Mesozoic age.
