Landscape
Argentina extends from subtropical northern lowlands to the cold south of South America. The Andes form its western mountain boundary, while the centre and east include extensive plains. Patagonia combines plateaus, mountains, lakes and a long Atlantic coast.
Iguazú Falls in the humid northeast contrasts strongly with the drier Patagonian interior and glaciated southern Andes. The Pampas are broad agricultural grassland country farther north. Latitude and mountain barriers create very different environments across the country.
