Amazon River

The Amazon River (occasionally River Amazon; Spanish: Río Amazonas, Portuguese: Rio Amazonas) of South America is one of the two longest rivers on Earth, the other being the Nile in Africa. The Amazon has by far the greatest total flow of any river, carrying more than the Mississippi, Nile, and Yangtze rivers combined. Its drainage area, called the Amazon Basin, is the largest of any river system. The Amazon could be considered the "strongest" (largest volume of water per second).
