Argentina is a large country in South America and is around three-tenths the size of the United States. Due to its size, there are very many geographical regions in it. These include the Pampas, Patagonia, Mesopotamia, the Andes Mountains, and Piedmont. The changes in altitude go from the rich agricultural plains of the Pampas to the high peaks of the Andes Mountains. The temperature in Argentina goes from boiling hot in the Pampas to freezing in Southern Patagonia. The Pampas is the site of the richest agricultural plains in all of South America. Most of the land is used for growing lots of cattle. The Pampas include the provinces of La Pampa, Buenos Aires, and others. Patagonia is a large cold plain that occupies most of Southern Argentina. Patagonia is the most sparsely populated place in the country because of the cold. Southern Patagonia is full of glaciers and icefields. The Argentinean Mesopotamia is between the Parana and Paraguay rivers. Mesopotamia means “between the rivers” in Greek. Mesopotamia is full of some of the most spectacular waterfalls in the country including Iguazu Falls. The Andes Mountains are a large group of parallel mountain ranges with high peaks and low valleys called “quebradas”. The Andes includes the highest peak in South America which is Cerro Aconcagua which is 6959 meters. The Andes are a roadblock that separates the western part of South America from the eastern part. If a person traveled through Argentina they would go through a variety of different climates and geographic sites.
