Amazon River
The Amazon River is the biggest river in South America and the second-longest river in the world at 6,400 kilometers in length, draining nearly 40% of the continent of South America. It also has the highest average flow volume of any river at 209,103 cubic meters per second, making it the biggest river in the world. According to a 2014 study published in a scholarly journal, the Mataro River, whose waters begin in Perus Cordillera Rumi Cruz, should be regarded as the source of the Amazon River.
Downstream, the Ucayali River is formed when the waters of the Mataro River combine with those of the Apurimac River and many other tributaries. After joining the Maranon River, the Ucayali becomes the primary channel of the Amazon. The Amazon River empties into the Atlantic near the Brazilian city of Belem. The Amazon River Basin occupies approximately 7,050,000 square kilometers. Kilometers and its whole watershed include parts of Bolivia, Brazil, Colombia, Ecuador, Peru, Guyana, and Venezuela on the South American continent.
