From the Northern Coast of South America to the Meeting of the Waters, Brazil3.1S 60W
This image stretches from the northenern coastline of South America, including Guyana, Suriname and French Guiana, across the Brazilian state of Roraima to the state of Amazonas.
Visible near the lower edge is the Amazon River. In the lower left corner, near the city of Manaus, the Meeting of Waters (Portuguese: Encontro das Águas) can be observed. It is the confluence between the Rio Negro, a river with dark (almost black coloured) water, and the sandy-coloured Amazon River or Rio Solimões, as it is known the upper section of the Amazon in Brazil. For 6 km (3.7 mi) the river’s waters run side by side without mixing. It is one of the main tourist attractions of Manaus, Brazil.
This phenomenon is due to the differences in temperature, speed and water density of the two rivers. The Rio Negro flows at near 2 km per hour at a temperature of 28°C, while the Rio Solimões flows between 4 to 6 km per hour a temperature of 22°C.
