It is also a river in South America that flows through many countries, with a total length of the river of at least 4,000 miles (6,400 km), which makes it slightly shorter than the Nile River, which is 4,132 miles(6649.8 km).

It has an area of about 2.7 million square miles (7 million square km) and stretches across about 1,725 miles (2,780 km) from north to south at its widest point. In summary, the Amazonia is the greatest river in South America and the largest drainage system in the world regarding the volume of its flow and the area of its basin.
