On the territory of which continent is the longest river in the world?

The longest river in the world is the Amazon. Its length is about 7000 kilometers. The Amazon flows through South America and into the Atlantic Ocean in Brazil. The Amazon flows through the territory of five states. In most of the Amazon, it is a navigable river, and somewhere over 1600 km, even ocean liners can move along it. But the most interesting thing is that not a single transport structure has yet been erected over the Amazon. The Amazon is a river that remains deep throughout the year.
