As in other states, in Argentina we can also divide rivers by slopesThese being those of the La Plata basin, the Atlantic basin, the Pacific basin, and in which the interior basins are grouped. To know in depth some of these water sources in this lesson from a TEACHER we are going to talk about the most important rivers of Argentina.
