Mountains not conveniently arranged along the edges of the continent 😤. Who designed this shit?

It depends on how you define a river. This map displays Rio de la Plata as a river, but that's debateable, officially it's an estuary. If you separate Parana and Uruguay rivers, than the Ob river basin in Asia is bigger than any of those.

too bad they aren't ranked by size. Also not as pretty as the OP.

Yeah I'd love to see more. The major rivers of China as well as the Niger and St. Lawrence would be awesome.

I read somewhere that the Amazon River used to run from east to west until about 6 million years ago when the Andes Mountains developed, reversing the course

Well, there's a little bunch of hills over there blocking it.

The glaciers and ice flow down to the ocean, here you can see the velocity of the ice there are a couple red streaks that could be called streams but they aren't the long narrow fast moving streams we'd call a river.
