the greatest river of south America and largest drainage system i the world in terms of the volume of its flow and the area of its basin the total length of the rival -as measured from the headwaters of the Ucayali-Apurimac rival system in southern pure-is at least 4,000 miles (6,400 km), which makes it slightly shorter then the Nile rival but still the equivalent of the distance from new York city to Rome.
VERY AMAZING
