The Amazon is the longest river in the world: 6150 km, but the Egyptians are not all of that opinion ... Born in the Peruvian Andes, it takes the name of "Rio Solimões" when it gets to Brazil where he makes half of its course. It is called "Rio Amazonas" from the confluence with the Rio Negro. It is also a gigantic river by its width (an average of 12 Km, and genuine freshwater inland seas at confluences) and 20 m depth all the way to the Peruvian border. Its annual flow is estimated at 200,000 m3 / sec., 5 times that of Zaire or 115 times that of the Rhone!
