Rainforest rivers     Click here for more detailed information about rainforests!

Due to the tremendous amount of rainfall they receive, tropical rainforests have some of the largest rivers in the world, like the Amazon, Mekong, Orinoco, and Congo. These mega-rivers are fed by countless smaller tributaries, streams, and creeks. For example, the Amazon alone has some 1,100 tributaries, 17 of which are over 1,000 miles (1,600 kilometers) long!
