Sediments in Amazon River Mouth, Brazil0.2N 50.2W
The Amazon River has the largest drainage basin in the world, about 7,050,000 square kilometres (2,720,000 sq mi), which accounts for approximately one-fifth of the world’s total river flow.
The width of the Amazon varies between 1.6 and 10 kilometres (1.0 and 6.2 mi) at low stage, but expands during the wet season to 48 kilometres (30 mi) or more. The river enters the Atlantic Ocean in a broad estuary about 240 kilometres (150 mi) wide. The mouth of the main stem is 80 kilometres (50 mi). Here, sediments can be seen pouring out of its wide mouth and into the Atlantic.
