Which river empties the most water into the ocean

Amazon River

Explanation:

The Amazon River is the river that has the largest amount of water in it, thus it is also the river that empties the most water into the ocean, more specifically in the Atlantic Ocean. The average discharge of the Amazon River is staggering 209,000 cubic meters per second, which accounts for approximately 20% of the total river discharge in the world. This river is the second longest in the world, after Nile, though there are some suggestions that it is actually the longest one. It is located in the South America, flowing in a roughly west-east direction, and it is forming the Amazon Basin which is home to the largest tropical rainforest in the world, the Amazon rainforest.
