The Great River Race
What is the longest river in the world?
If you lined up every river on Earth for a race to the sea, which one would win the marathon? For most of history, everyone agreed: the Nile River in Africa, winding 4,132 miles from central Africa to the Mediterranean. But then some scientists grabbed better maps and said, "Wait — we need to recount."
The challenger is the Amazon River in South America. It's definitely the fattest river — it dumps more water into the ocean every single day than any other river on the planet. But is it the longest? That depends on where you say it starts.
