Answer: Nile
Measurements vary depending on where the source is placed. Some studies argue the Amazon is slightly longer than the Nile.

The arapaima can grow to about three meters long and must come to the surface to breathe air.
Q9: What is the tidal wave that rushes up the Amazon called?

Amazon River Quiz – The Greatest River on Earth

The Amazon is the world's largest river by volume, carrying more water than any other. It starts in the Peruvian Andes, crosses Brazil and pours into the Atlantic so powerfully that fresh water can be found far out at sea. In the rainy season its waters rise by many meters and flood vast forests.

The river supports astonishing wildlife: thousands of fish species, pink river dolphins, giant otters, caimans and anacondas. Its flooded forests, called várzea and igapó, act as nurseries for fish and feed millions of people along its banks.

The Amazon also shapes the planet's climate. Its rainforest releases water vapor that forms flying rivers of moisture over South America. Deforestation, dams and mining threaten the river system, so protecting it is a global concern.
