Sediments From Rio de la Plata Pass Buenos Aires, Argentina34.6S 58.3W
Argentina has an area of 1,073,520 sq mi (2,780,403 sq km) and a population (2009 est.) of about 40,276,000. The capital is Buenos Aires, visible near the center of the image along the lower shores of the Rio de la Plata estuary (neighboring country Uruguay is visible along the upper shores). Dense sediments flow out of the estuary and into the Atlantic Ocean.
Argentina can be divided into four general regions: the North, the Pampas, Patagonia, and the Andes Mountains. The subtropical plains in the northeast are divided by the Paraná River into Mesopotamia to the east and Gran Chaco to the west and north.
