South America's Amazon River is the world's largest because it carries more water to the sea than any other river. The Amazon's discharge at its mouth is approximately 7 million cubic feet per second.

The biggest river in the world is actually the nile river which is 6693 kilometres long(4160 miles). The second biggest river in the world is the amazon which is 6436 kilometres long (4000 miles).

The Amazon is the greatest river in the world by so many measures; the volume of water it carries to the sea (approximately 20% of all the freshwater discharge into the oceans), the area of land that drains into it, and its length and width. It is one of the longest rivers in the world and, depending upon who you talk to, is anywhere between 6,259km/3,903mi and 6,712km/4,195mi long. For the last century the length of the Amazon and the Nile Rivers have been in a tight battle for title of world's longest river. The exact length of the two rivers varies over time and reputable sources disagree as to their actual length. The Nile River in Africa is reported to be anywhere from at 5,499km/3,437mi to 6,690km/4,180mi long. But there is no question as to which of the two great rivers carries the greater volume of water - the Amazon River. At its widest point the Amazon River can be 11km/6.8 mi wide during the dry season. The area covered by the Amazon River and its tributaries more than triples over the course of a year. In an average dry season 110,000 square km of land are water-covered, while in the wet season the flooded area of the Amazon Basin rises to 350,000 square km. When the flood plains and the Amazon River Basin flood during the rainy season the Amazon River can be up to 40km/24.8 mi wide. Where the Amazon opens at its estuary the river is over 325km/202 mi wide! Because the Amazon drains the entire Northern half of the South American continent (approx. 40% landmass), including all the torrential tropical rains that deluge the rainforests, it carries an enormous amount of water. The mouth of the Amazon River, where it meets the sea, is so wide and deep that ocean-going ships have navigated its waters and traveled as far inland as two-thirds the way up the entire length of the river.

THE NILE!!!!! More Info: -It is also the worlds oldest river

I am not sure what you mean by "biggest". From the previous answers you can make up your own mind. The Nile (both the blue and white nile together) is the longest river in the world, while the Amazon moves the most water and is the widest river, but only the second largest. FYI the third longest is the Yangste River, and the fourth longest is the Mississippi.

the nile is the longest and the amazon is the widest all believe me!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Amazon in terms of the volume of water. It's also the world's second longest river, after the Nile.

I think it's DE-NIAL. ;-) Seriously, I'm pretty sure it's the Amazon, followed by the Nile. But, of course, I could be wrong.
