The Amazon Rainforest is a moist broadleaf forest in the Amazon Basin of South America. The area, also known as Amazonia, the Amazon jungle or the Amazon Basin, encompasses seven million square kilometers (1.7 billion acres), though the forest itself occupies some 5.5 million square kilometers (1.4 billion acres), located within nine nations: Brazil (with 60 percent of the rainforest), Peru (with 13 percent of the rainforest, second after Brazil), Colombia, Venezuela, Ecuador , Bolivia, Guyana, Suriname, and French Guiana. States or departments in four nations bear the name Amazonas after it. The Amazon represents over half of the planet's remaining rainforests and comprises the largest and most species-rich tract of tropical rainforest in the world
