The Amazon produces approximately 20 percent of all the water that the world’s rivers pour into the oceans on its own.
The Amazon collects water from just over 40 percent of South America’s Landmass, through the thousands of tributaries that join the main branch of the Amazon river. Of these tributaries, 17 are over 1600(1000 miles) kilometres long.
