The Amazon is the greatest river in the world by the volume of water it carries to the sea (approximately 20% of all the freshwater discharged into the oceans), by the area of land that drains into it, and  by its length and width. At approximately 4,000 miles, it is one of the longest rivers in the world.

Shown in the photo is the convergence of the Amazon and Rio Negra.
