What is the biggest river by volume on earth?

The Amazon River is widely recognized as the largest river by volume on earth. Located in South America, the Amazon River has an astonishing average discharge of approximately 209,000 cubic meters per second, making it more voluminous than the next seven largest rivers combined. Spanning a length of approximately 6,400 kilometers, this mighty river is truly a force of nature.

The Amazon River originates from the Amazonian Andes and flows through multiple countries, including Peru, Colombia, and Brazil, before eventually emptying into the Atlantic Ocean. Its massive volume can be attributed to the vast network of tributaries that contribute to its flow, resulting in an expansive river system. The Amazon rainforest, often referred to as the lungs of the Earth, plays a crucial role in maintaining the river’s volume, as it receives significant precipitation throughout the year.
