Sediments in Amazon River Mouth, Brazil0.6N 50W
Despite some cloud cover, thick sediments can be seen spilling forth from the mouth of the Amazon River in South America. It is the second longest river in the world and by far the largest by waterflow.
The width of the Amazon varies between 1.6 and 10 kilometres (0.99 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).
