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.[1]
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.
