| abstract | - South America is the southern continent of America, situated entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere. 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. America was named in 1507 by cartographers Martin Waldseemüller and Matthias Ringmann after Amerigo Vespucci, who was the first European to suggest that the newly discovered lands were not India, but a New World unknown to Europeans. South America has an area of 17,840,000 sq km (6,890,000 sq mi), or almost 3.5% of the Earth's surface. As of 2005, its population was estimated at more than 300,000,000. South America ranks fourth in area (after Asia, Africa, and North America) and third in population (after Asia and Africa).
