Uruguay Weather and Climate

According to COUNTRYAAH, The border with Argentina is marked by the Uruguay River. The official name of the state, República Oriental del Uruguay, is due to the fact that in colonial times this region corresponded to the Banda Oriental of the Spanish viceroyalty of the Río de la Plata. A rich, democratic nation, known for its highly advanced social legislation, it was formerly referred to as “Switzerland of South America”. The good relationship between surface and population, small in number, was the basis of the extraordinary economic growth, centered on its greatest wealth, livestock, and a consequent social well-being. This solid prosperity, which failed both for internal reasons (a production disadvantage due to the same reasons that had made it a thriving country) and for external causes (the crises of the neighboring states which occurred in the 1960s), has taken over a development measured, thanks also to economic cooperation and integration with the markets of the rest of the continent.


Uruguay has a very simple morphology being made up of coastal plains and areas intensely flattened by erosion, which has given them a gently undulating appearance: the average altitude is in fact around 100 m, while the modest mountain ranges, which do not they exceed 500 m in height (501 m reaches an isolated eminence in the south of the country), they cover just 3% of the total area. The territory represents the extreme southern section of the highlands forming part of the great Precambrian shield of Brazil. The rocks (mainly gneiss and granite), intensely metamorphosed and fractured, emerge in the open in the southern part of the country, reaching as far as the coasts of the Río de la Plata, where the (known locally as barrancos); in northern Uruguay, on the other hand, they are generally covered by powerful sedimentary series of sandstones, argillites and limestone from the Devonian (Paleozoic) to Triassic (Mesozoic) ages: they are also remarkably peneplanate and fractured and in several places erosive denudation phenomena have caused uncovered the crystalline substrate. There are numerous basaltic lava expansions, which occurred in the Cenozoic, in the context of the intense orogenetic activity of that era. Neozoic deposits, both continental and marine, cover the coastal strips and the lower areas of the valley bottoms. The relief is essentially divided into two main alignments that cross the country from NE to SW, the hilly ridges of the Cuchilla de Haedo, to the NW, and of the Cuchilla Grande, to the SE, delimiting the wide basin of the Río Negro; from them they branch out in various lower directions and gentle undulations, which are extinguished with rocky protrusions and barrancos on the Río de la Plata and with flat surfaces, edged with cords of sandy dunes and lagoons, including the vast Merín Lagoon (in Portuguese called Lagoa Mirim), on the Atlantic.
