In its upper stretches, above its confluence with the Rio Negro, the Amazon is called Solimões in Brazil; however, in Peru, Colombia and Ecuador, as well as the rest of the Spanish-speaking world, the river is generally called the Amazon downstream from the confluence of the Marañón and Ucayali rivers in Peru. The Ucayali-Apurímac river system is considered the main source of the Amazon, with its main headstream being the Carhuasanta glacial stream flowing off the Nevado Mismi mountain.
The width of the Amazon is between 1.6 and 10 kilometers (1.0 and 6.2 mi) at low stage but expands during the wet season to 48 kilometers (30 mi) or more. The river enters the Atlantic Ocean in a broad estuary about 240 kilometers (150 mi) wide. The mouth of the main stem is 80 kilometers (50 mi).
Because of its vast dimensions, it is sometimes called "The River Sea".
The total volume of water discharging from the Amazon river in a year is about 6,591 cubic kilometers (to compare, the water volume of Lake Baikal is 23,615 cubic kilometers).
