The Americas are the lands of the Western Hemisphere or New World consisting of the Continent s of North America 1 and South America with their associated Island s and Region s. The Americas cover 8.3% of the Earth 's total surface area (28.4% of its land area) and contain about 14% of the Human Population (about 900 million people). ''The Americas'' may alternatively be referred to as ''''' America '''''; however, ''America'' may be ambiguous as it can refer to either this entire Landmass or just the United States Of America . HISTORY See Also: History of the Americas Formation South America broke off from Western Gondwanaland around 135 million BCE, forming its own continent.2 Starting around 15 million BCE, the collision of the Caribbean Plate and the Pacific Plate resulted in a series of volcanoes along the border that created a number of islands. The gaps in the archipelago of Central American filled in with material eroded off North America and South America, plus new land created by continued volcanism. By 3 million BCE, the continents of North America and South America were linked by the Isthmus Of Panama , thereby forming the single landmass of the Americas.3 Settlement See Also: Pre-Columbian trans-oceanic contact Archaeological finds establish the widespread presence of the Clovis Culture in North America and South America around 10000 BCE .4 Whether this is the first migration of humans into North America and South America is disputed, with Alternative Theories holding that humans arrived in North America and South America as early as 40000 BCE. |
