3 days ago - Geological studies suggest that for millions of years, the Amazon River flowed in the opposite direction – from east to west. Eventually the Andes Mountains formed, blocking its flow to the Pacific Ocean and causing it to switch directions to its current mouth in the Atlantic Ocean.

What's up with the Amazon river mouth? Why does it seem split in two branches (the "main" one and Belém) ? Is this man-made, because I've never seen such a river mouth shape anywhere else.
The river in Belém is the Tocantins River which is not a part of the Amazon. The river that goes around Marajó Island into the Amazon is the Pará River, which is supplied by the Tocantins. More on reddit.com

Is it just a coincidence the mouth of the Amazon river is at the equator?
Just a coincidence. There are rivers all over the world that empty at all different latitudes Rivers flow from the highest altitude to the lowest, and the Amazon's path just follows the geography that happens to take it where it does. More on reddit.com

I knew that the Amazon is large ofc, but never really thought how close it is to the Pacific ocean in the western part. Instead of the water flowing into the Pacific, it travels the whole continent to flow into the Atlantic. Neat.
It’s always good to remember the Amazon River breaks almost every conversation about rivers; It is the largest river by volume, longest river in the world (depending on how you measure, the Nile is 1 or 2), the largest river with no dam, the mouth of Amazon is largest in the world, largest by watershed, least amount of incline from source to mouth (again depending on how you count) and several more records. The Amazon River is an absolute behemoth with no real comparison. It contains about 1/5 of all river discharge into the worlds oceans, more than the next seven rivers combined More on reddit.com

Coming a close second after the Nile as the world’s longest river, the Amazon River sets the record in terms of the sheer volume of water that it carries – a mind-boggling average discharge of 219,000 m3/sec of water.2 It is estimated that approximately one-sixth of all fresh water that drains into the world's oceans goes through the 320-km-wide delt of the Amazon, where it meets the Atlantic Ocean.

Where the Amazon River's mouth sits today, there was once a highland that allowed for this westerly flow.

March 31, 2023 - We started near the river mouth at the city of Macapá and navigated upstream to Óbidos. Then we followed a water mass downstream (an approach called a Lagrangian mode) while also sampling the major clear-water tributaries—the Xingu and Tapajós rivers—each of which discharges a volume of water on the same order of magnitude as the Mississippi River. Fig. 1. Our initial study domain for the lower Amazon River extended from Óbidos to the city of Macapá (black), including the Tapajós and Xingu rivers.
