South America is one of the most biodiverse continents on earth.
South America is home to many interesting and unique species of animals including the llama, anaconda, piranha, jaguar, vicuña, and tapir.
The average annual temperatures in the Amazon basin oscillate around 27 °C, with low thermal amplitudes and high rainfall indices.
Between the Maracaibo Lake and the mouth of the Orinoco, predominates an equatorial climate of the type Congolese, that also includes parts of the Brazilian territory.
In addition to this, the ABC islands of the Kingdom of the Netherlands, Trinidad and Tobago, and Panama may also be considered part of South America.South Georgia and the South Sandwich Islands may be associated with either South America or Antarctica.The distribution of the average temperatures in the region presents a constant regularity from the 30° of latitude south, when the isotherms tend, more and more, to be confused with the degrees of latitude.South America has an area of 17,840,000 square kilometers (6,890,000 sq mi).Its population as of 2016 South America ranks fourth in area (after Asia, Africa, and North America) and fifth in population (after Asia, Africa, Europe, and North America).The remaining countries and territories are divided among three regions: The Andean States, the Guianas and the Southern Cone.Traditionally, South America also includes some of the nearby islands.The reference to South America instead of other regions (like Latin America or the Southern Cone) has increased in the last decades due to changing geopolitical dynamics (in particular, the rise of Brazil).It is bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean; North America and the Caribbean Sea lie to the northwest.The continent is generally delimited on the northwest by the Darién watershed along the Colombia–Panama border, although some may consider the border instead to be the Panama Canal.Geopolitically and geographically Almost all of mainland South America sits on the South American Plate.
