The Parana and Uruguay rivers flow south through Rio de la Plata, Argentina and along the Argentina-Uruguay border to empty into the Rio de la Plata. Also the southern Atlantic Ocean in this true-color Aqua MODIS image from January26, 2002. Therefore because of the relative calm surface of the Rio and the angleof the Sun relative to the MODIS instrument.
Therefore it is possible to see the current of the river flowing out into the Atlantic, visible as a coffee-brown and black streak against the tan and gray-blue surrounding waters.
Also visible is the city of Buenos Aires, Argentina’s capita land one of the biggest cities in South America. Buenos Aires sits on the upper southern side of the Rio, very near the mouths of the Parana and Uruguay rivers, and is visible as a large, spidery shaped gray patch.
Uruguay’s capital city, Montevideo, is also visible on the Rio,appearing as a spidery, though smaller, gray patch about parallel with Buenos Aires on a southern tip of Uruguay. It is just north of where the Rio’s current turns from coffee-brown to a black color. Although Rio de la Plata, Argentina have amazing weather and the green patchy landscape the weather can cause it to look different.
