As to its end point, the Amazon has three outlets to the Atlantic Ocean: two on the northern side of Marajó Island in Brazil and one to the island’s south that joins the Pará River. Scientists have typically selected one of the northern outlets, since the Pará is an estuary of the Tocantins River, which is technically separate from the Amazon.

The word Amazon itself may be derived from the Iranian compound *ha-maz-an- " (one) fighting together" or ethnonym *ha-mazan- "warriors", a word attested indirectly through a derivation, a denominal verb in Hesychius of Alexandria 's gloss "ἁμαζακάραν· πολεμεῖν.

10 The lack of bridges is due, in part, to the seasonal changes in the Amazon River bed.

The Amazon's soft river banks erode as with the seasonal inundation of rainwater, making previously sturdy areas into unstable floodplains. 11 Any bridge to cross the Amazon River would need to be incredibly long to have sure footing.

Where does the rain come from in the Amazon basin?
The main influx of atmospheric water vapour into the basin comes from the east. About half of the precipitation that falls originates from the Atlantic Ocean; the other half comes from evapotranspiration from the tropical forest and associated convectional storms. Rainfall in the lowlands typically ranges from 60 to 120 inches (1,500 to 3,000 mm) annually in the central Amazon basin (e.g., Manaus). On the eastern and northwestern margins of the basin, rainfall occurs year-round, whereas in the central part there is a definite drier period, usually from June to November. Manaus has experienced as many as 60 consecutive days without rain. Moreover, in 2005 the Manaus region experienced a devastating drought, which caused parts of the river to dry up; this made transportation difficult, depleted drinking supplies, and left millions of rotting fish in the riverbed. Such extreme periods of drought are uncommon to the Manaus region, but fluctuations in the river’s level—thought to be related to climatic events and continued deforestation in the area—have continued to be of concern. The dry season is not sufficiently intense to arrest plant growth, but it may facilitate the onset and spread of fires, whether arsonous or natural. To the west the Andes form a natural barrier that prevents most of the water vapour from leaving the basin. The influence of mountains on rainfall is indicated by the high levels of precipitation in the upper piedmont and by the cloud-steeped Andean flanks, which feed the rivers that form a large part of the Amazon system. The highest amounts of precipitation, up to 140 inches (3,500 mm), are recorded in the upper Putumayo along the Colombian border.
