Natural Regions Of Chile
Because Chile extends from a point about 625 kilometers north of the Tropic of Capricorn to a point hardly more than 1,400 kilometers north of the Antarctic Circle, within its territory can be found a broad selection of the Earth's climates. In 1950, CORFO defined, following criteria of geographic and economic homogeneity, six regions in continental Chile: ''Norte Grande'', ''Norte Chico'', ''Núcleo Central'', ''Concepción y La Frontera'', ''Los Lagos'' and ''Los Canales''. Although this territorial division was never used to define administrative entities (as the current Regions of Chile), the natural regions continue to be used for reference purposes. Overview These natural regions are ordered from north to south and reduced to five natural regions: Each has its own characteristic vegetation, fauna, climate, and, despite the omnipresence of both the Andes and the Pacific, its own distinct topography. Norte Grande Most of the region is covered by the Atacama Desert and h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glaciar Grey, Parque Nacional Torres Del Paine, Chile4
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. It acquires distinguishing features, such as crevasses and seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand. Between latitudes 35°N and 35°S, glaciers occur only ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Puna Grassland
The puna grassland ecoregion, of the montane grasslands and shrublands biome, is found in the central Andes Mountains of South America. It is considered one of the eight Natural Regions in Peru,Pulgar Vidal, Javier: Geografía del Perú; Las Ocho Regiones Naturales del Perú. Edit. Universo S.A., Lima 1979. First Edition (his dissertation of 1940): Las ocho regiones naturales del Perú, Boletín del Museo de historia natural „Javier Prado“, n° especial, Lima, 1941, 17, pp. 145-161. but extends south, across Chile, Bolivia, and western northwest Argentina. The term puna encompasses diverse ecosystems of the high Central Andes above 3200–3400 m. Location The puna is found above the treeline at 3200–3500 m elevation, and below the permanent snow line above 4500–5000 m elevation. It extends from central Peru in the north, across the Altiplano plateau of Peru, Chile and Bolivia, and south along the spine of the Andes into northwest Argentina. Other sour ...

Aconcagua River
The Aconcagua River is a river in Chile that rises from the conflux of two minor tributary rivers at above sea level in the Andes, Juncal River from the east (which rise in the Nevado Juncal) and Blanco River from the south east. The Aconcagua river flows westward through the broad Aconcagua valley and enters the Pacific Ocean near the city of Concon, north of Valparaíso. The river has a course of about , and its waters irrigate the most populous sections of the Chilean provinces of San Felipe de Aconcagua and Los Andes, being the most important economic resource of those regions. During the course of the Aconcagua river, it receives contributions from many others rivers and swamps, reaching a mean flow of . The Aconcagua River valley was used as the route of the Transandine Railway on the Chilean side. The river flows alongside Chile Route 5 from Llaillay to La Calera. For much of their lengths, the two separate stretches of Chile Route 60 follow the course of the ri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Valparaíso Region
The Valparaíso Region ( es, Región de Valparaíso, links=no, ) is one of Chile's 16 first order administrative divisions.Valparaíso Region, 2006 With the country's second-highest population of 1,790,219 , and fourth-smallest area of , the region is Chile's second most densely populated after the Santiago Metropolitan Region to the southeast. The region also includes the remote Easter Island (Rapa Nui) in the Pacific Ocean. Its capital is the port city of Valparaíso; other important cities include Viña del Mar, Quillota, San Felipe, Quilpué, Villa Alemana, and San Antonio. Administration As a region, Valparaíso is a first-level administrative division. Since 2021 the region is governed by the governor, who is elected by popular vote. The current governor is Rodrigo Mundaca ( Broad Font). Geography and natural features The region is on the same latitude as the Santiago Metropolitan Region. Its capital is Valparaíso, which is the site for the National Congre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coquimbo Region
The Coquimbo Region ( es, Región de Coquimbo, ) is one of Chile's 16 regions (first order administrative divisions). It is bordered by Atacama to the north, Valparaíso to the south, Argentina to the east, and the Pacific Ocean to the west. It is approximately north of the national capital, Santiago. The capital and largest city is La Serena. Other important cities include the seaport Coquimbo and the agricultural centre Ovalle. Geography and ecology The Coquimbo Region forms the narrowest part, or 'waist' of Chile, and is hence one of the country's more mountainous regions, as the Andes range runs closer to the sea than elsewhere. The region has notable marine species as well as taxa that are associated with the mountainous regions. With respect to marine organisms, the upwelling areas encourage bioproductivity off of this Pacific Coast area of Chile. In the southern mountainous areas of the Coquimbo Region, the rare and endangered Chilean Wine Palm is found, who ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chilean Iron Belt
The Chilean Iron Belt is a geological province rich in iron ore deposits in northern Chile. It extends as a north-south beld along the western part of the Chilean regions of Coquimbo and Atacama, chiefly between the cities of La Serena and Taltal. The belt follows much of the Atacama Fault System and is about 600 km long and 25 km broad. Iron oxide-apatite, iron oxide copper gold ore deposits (IOCG) and manto-type copper and silver are the main types of deposits. Iron-apatite and IOCG are considered to have different origins. Manto-type deposits are concentrated in the northern part of the belt and are chiefly emplaced on rocks of La Negra Formation. The ores of the Chilean Iron Belt formed in separate pulses in the Cretaceous period as result of magmatic and hydrothermal processes. At least part of the iron oxide-apatite rock originated from molten iron in the form of lava, tephra. and intrusions. Thus iron oxide apatite magma cooled into rock variously from surface volcano ...

A slab refers to the subducting lower plate. Although, some would characterize flat slab as any shallowly dipping lower plate as in western . Flat slab |
Flowering Desert (Chile)
A desert bloom is a climatic phenomenon that occurs in various deserts around the world. The phenomenon consists of the blossoming of a wide variety of flowers during early-mid spring in years when rainfall is unusually high. The blossoming occurs when the unusual level of rainfall reaches seeds and bulbs that have been in a latent or dormant state, and causes them to germinate and flower in early spring. It is accompanied by the proliferation of insects, birds and small species of lizards. Around the world Chile In the Atacama Desert, a desert bloom ( es, desierto florido) occurs between the months of September and November in years when rainfall is unusually high. Normally, the Atacama Desert receives less than of rain a year. At its height, the phenomenon can be seen from just south of the city of Vallenar to just north of the city of Copiapó throughout the coastal valleys and Chilean Coast Range from September to November. Climatically, the event is related to the El ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transverse Valleys
The Transverse Valleys (Spanish: ''Valles transversales'') are a group of transverse valleys in the semi-arid northern Chile. They run from east to west (traversing Chile), being among the most prominent geographical features in the regions they cross. They are located in the Chilean regions of Valparaíso, Coquimbo Coquimbo is a port city, commune and capital of the Elqui Province, located on the Pan-American Highway, in the Coquimbo Region of Chile. Coquimbo is situated in a valley south of La Serena, with which it forms Greater La Serena with more than ..., and Atacama. They share some characteristics, such as reaching the Pacific Ocean without passing through an Intermediate Depression, being rather deep and dissecting the landscape, concentrating most agriculture and population in the areas through which they pass, and being intensively cultivated. They are one of the defining elements of the Natural regions of Chile, Chilean natural region of Norte Chico, Chile, Norte Chi ...

Semi-arid Climate
A semi-arid climate, semi-desert climate, or steppe climate is a dry climate sub-type. It is located on regions that receive precipitation below potential evapotranspiration, but not as low as a desert climate. There are different kinds of semi-arid climates, depending on variables such as temperature, and they give rise to different biomes. Defining attributes of semi-arid climates A more precise definition is given by the Köppen climate classification, which treats steppe climates (''BSk'' and ''BSh'') as intermediates between desert climates (BW) and humid climates (A, C, D) in ecological characteristics and agricultural potential. Semi-arid climates tend to support short, thorny or scrubby vegetation and are usually dominated by either grasses or shrubs as it usually can't support forests. To determine if a location has a semi-arid climate, the precipitation threshold must first be determined. The method used to find the precipitation threshold (in millimeters): *mult ...

Norte Chico, Chile
The Norte Chico (''Small North'', ''Near North'', ''Little North'') is one of the five natural regions into which CORFO divided continental Chile in 1950. Its northern border is formed by the limit with the Far North, to the west lies the Pacific Ocean, to the east the Andes mountains and Argentina, and to the south the Zona Central natural region. Although from a strictly geographic point of view, this natural region corresponds to the Chilean territory between the rivers Copiapó and Aconcagua, traditionally the Norte Chico refers to the zone comprising the regions of Atacama and Coquimbo. This region was home to the Diaguita people. Geography The near north (Norte Chico) extends from the southern border of the Atacama Desert to about 32° south latitude, or just north of Santiago. It is a semiarid region whose central area receives an average of about 25 mm of rain during each of the four winter months, with trace amounts the rest of the year. The near north is ...
