largest global rivers
The biggest river in the world, measured by the amount of water that flows down it, is the Amazon. On average 120,000 cubic metres (about 20 swimming pools' worth) of water flows out of its mouth every second. firstly, the term LARGEST is quite wrong. You can ask which is the longest or biggest river.
The Orinoco in Venezuela apart from being the fourth largest river of the world is also among the longest rivers of South America. It has a drainage basin of 880,000 square km and an average discharge of 33,000mÂ³/second. It outflows into the Atlantic.
