Argentina
Argentina, officially the Argentine Republic (Spanish: República Argentina, Nación Argentina (Argentine Nation) for many legal purposes), is a South American country, second in size in the continent to Brazil and eighth in the world. Argentina occupies a continental surface area of 2,766,890 km² (1,078,000 sq mi) between the Andes mountain range in the west and the southern Atlantic Ocean in the east and south.
It is bordered by Paraguay and Bolivia in the north, Brazil and Uruguay in the northeast, and Chile in the west and south. The country claims the British controlled territories of the Falkland Islands (Spanish: Islas Malvinas) and South Georgia and the South Sandwich Islands. Under the name of Argentine Antarctica, it claims 969,464 km² (374,312 sq mi) of Antarctica, overlapping other claims made by Chile and the United Kingdom.
Etymology
"Argentina" derives from the Latin argentum (silver). When the first Spanish conquistadors discovered the Río de la Plata, they named the estuary Mar Dulce ('Sweet Sea', as in a fresh water sea). Indigenous people gave gifts of silver to the survivors of the shipwrecked expedition, who were led by Juan Díaz de Solís. The legend of Sierra del Plata – a mountain rich in silver – reached Spain around 1524, and the name was first seen in print on a Venice map from 1536. The source of the silver was the area where the city of Potosí was to be founded in 1546. An expedition that followed the trail of the silver up the Paraná and Pilcomayo rivers finally reached the source only to find it already claimed by explorers who reached it from Lima, the capital of the Viceroyalty of Peru.
The name Argentina was first used extensively in the 1612 book Historia del descubrimiento, población, y conquista del Río de la Plata (History of the discovery, population, and conquest of the Río de la Plata) by Ruy Díaz de Guzmán, naming the territory Tierra Argentina (Land of Silver). Traditionally, the British English name for the country is "The Argentine", but this is no longer in common use.
Geography

The total surface area of Argentina (not including the Antarctic claim), is as follows:
- Total: 2,766,890 km²
- Land: 2,736,691 km²
- Water: 30,200 km²
Argentina is nearly 3,700 km long from north to south, and 1,400 km from east to west (maximum values). It can roughly be divided into four parts: the fertile plains of the Pampas in the center of the country, the source of Argentina's agricultural wealth; the flat to rolling, oil-rich plateau of Patagonia in the southern half down to Tierra del Fuego; the subtropical flats of the Gran Chaco in the north, and the rugged Andes mountain range along the western border with Chile.
The highest point above sea level in Argentina is located in Mendoza. Cerro Aconcagua, at 6,962 meters (22,834 feet), is the highest mountain in the Americas, the Southern, and Western Hemisphere. The lowest point is Laguna del Carbón in Santa Cruz, −105 meters (−344 ft) below sea level. This is also the lowest point on the South American continent. Due to the higher gravity force in Laguna del Carbón, a pendulum clock, if not corrected, will advance 24 seconds a day. The geographic center of the country is located in south-central La Pampa province.
The country has a territorial claim over a portion of Antarctica (unrecognized by any other country), where, from 1904, it has maintained a constant presence.

The hottest and coldest temperature extremes recorded in South America have occurred in Argentina. A record high temperature of 49.1°C (120.4 °F), was recorded at Villa de María, Córdoba on January 2, 1920. The lowest temperature recorded was −39.0 °C (−38.2 °F) at Valle de los Patos Superior, San Juan, July 17, 1972.
Major winds in Argentina include the cool Pampero blowing on the flat plains of Patagonia and the Pampas after a cold front; the Viento Norte, a warm wind that can blow from the north in mid and late winter creating mild conditions; and the Zonda, a hot and dry wind (see also Föhn wind), affecting west-central Argentina. Squeezed of all moisture during the 6,000 meter descent from the Andes, Zonda winds can blow for hours with gusts up to 120 km/h, fueling wildfires and causing damage. When the Zonda blows (June-November), snowstorms and blizzard (viento blanco) conditions usually affect the higher elevations.
The Sudestada (literally "southeaster") could be considered similar to the Noreaster, though snowfall is rarely involved (but is not unprecedented). Both are associated with a deep winter low pressure system. The sudestada usually moderates cold temperatures but brings very heavy rains, rough seas, and coastal flooding. It is most common in late autumn and winter along the coasts of central Argentina and in the Río de la Plata estuary.
The southern regions, particularly the far south, experience long periods of daylight from November to February (up to nineteen hours), and extended nights from May to August. All of Argentina uses UTC-3 time zone. The country does not observe daylight saving time.
Population
The National Institute of Statistics and Census of Argentina (INDEC) 2001 census showed the population of Argentina was 36,260,130. It ranks third in South America in total population and 30th globally. The 2005 estimate is for a population of 38,747,000. Argentina's population density is 14 inhabitants per square kilometer. However, the population is not evenly distributed: areas of the city of Buenos Aires have a population density of over 14,000 inhab./km², while Santa Cruz province has less than 1 inhab./km². Argentina is the only nation in South America with a net positive migration rate, of about +0.4 persons.
