The Tropic of Capricorn (or Southern Tropic ) is a circle of latitude that contains a subsolar point at the December (or south) turning point. Thus the southernmost latitude where the Sun can be directly above. The northern equivalent is the Tropic of Cancer.

The Tropic of Capricorn is one of five large circles of latitude that marks the Earth map. On June 9, 2018, the latitude is 23 Â ° 26? 12.8 Â ° (or 23.43689 Â °) south of the Equator, but gradually moving northward, currently at a rate of 0.47 seconds arc, or 15 meters, per year.

Geography and environment

Tropic of Capricorn is the dividing line between the Southern Temperate Zone to the south and the tropics to the north. The Northern Hemisphere equivalent to Tropic of Capricorn is Tropic of Cancer.

The Tropic of Capricorn position is not fixed, but varies in complex ways over time; look under the circles of latitude for information.

In Australia, the Tropic regions have some of the most varied rainfall in the world and thus even wetlands can not be generally planted, because irrigation sources are always dry in years of drought. In southern Africa, where rainfall is more reliable, agriculture is possible, although yields are low even with fertilizer.

In South America, while in continental crater lands are almost as old as in Australia and South Africa, the presence of young and growing geologic Andes means that this region is on the west side of the subtropical anthropyclons and thus receives warm and moist air. from the Atlantic Ocean. Consequently, Brazil's bordering areas with the Tropic are a very important agricultural area, producing large quantities of crops such as sugar cane, and natural rainforest vegetation is almost entirely cleared, except for some of the remaining Atlantic forest patches. Further south in Argentina, the temperate meadows of the Pampas region are one of the most productive agricultural areas in the world, producing wheat, soybeans, corn and beef, making this country one of the world's largest agricultural exporters, similar to its role. played by the Prairies area in Canada.

To the west of the Andes, however, the Humboldt Flow made the conditions extremely arid, creating the Atacama Desert, one of the driest in the world, so there is no glacier among VolcÃÆ'¡n Sajama at 18? 30'S and Cerro Tres Cruces at 27? S. Vegetation here is virtually non-existent, although on the eastern slopes of Andes rainfall is sufficient for rainfed agriculture.

Further south in the Patagonia region, divided between Argentina and Chile, the climate becomes colder, with heavy snowfall in the winter months and throughout the year. In the western part of Patagonia, the climate is more humid, and is dominated by fjords, forests including needle-tree species and lakes due to the melting currents from permafrost at the top of the Andes mountains that divide the area. This makes the area a popular destination for skiing and winter sports, especially in the town of Bariloche and the surrounding area of ​​Argentina. In the Eastern part of the climate Patagonia is generally cold and dry steppes, with high mesas and strong wind conditions.

The southern end of Tierra del Fuego and other South Atlantic islands have sub-Antarctic climate conditions.

Name

The Tropic of Capricorn is so named because, when its name about 2,000 years ago, the sun is also in the direction of the constellation Capricornus ( capricorn is Latin for the goat horn ) at a turning point the December sun. In modern times the sun appears in the constellation Sagittarius over the years. This change is due to the precession of the equinox. The word "tropic" itself comes from the Greek trope (?????) , which means change, change direction or state , referring to the fact that the sun appears to "return "on the soltis.
