Which rivers in South America belong to the rivers of the Atlantic Basin?

Most of the South American rivers belong to the Atlantic basin. Among them, we can mention the Amazon, the largest river of this continent and the planet as a whole. This river has hundreds of tributaries, which, together with the main artery, belong to the Atlantic. The Parana, the second longest river on the continent, also belongs to the Atlantic Ocean basin. The great river of Patagonia, Uruguay, also flows into the indicated ocean. Also worth noting is the Rio Negro, which flows just south of them. The Orinoco River, which is located in the north of the continent, also deserves mention.
