OUR ARGENTINEAN
DIVISIÓN REGIONAL
            The current geography divides the Argentina in eight regions: the Llanura Platense, the Meseta Subtropical, the Noroeste, the Sierra Pampeanas, the Cuyo,the Patagonia, the Mar Argentino and the Antártida Argentina.
            On the other hand, using identical approaches diferenciandores sebregiones can be determined that, in exchange for sacrificing their extension, they present bigger internal homogeneity. 
            A division politicoterritorial also exists (the county) and a division politicoadministrativa (department or party).
SIERRAS PAMPEANAS
            Of old structure, the Sierras Pampeanas are formed by blocks of the solid one of Brasilia, fractured by the push of the Andean plegamiento third; some ascended originating the mountains and other they collapsed giving place to basins that, according to their form, they receive the names of valleys, fields, bolsones or plains. 
The mountains are very high to the N of the system, highlighting the hill of the Bolsón, in the mountain of the Aconquija. Toward the S the mountains are lower and the flat areas prevail regarding the mountainous chains. Due to their continental situation, the winds of the Atlantic already arrive very out of humidity and they only discharge precipitations on the oriental hillsides of the cords that are the E. more The rest of the region he/she only receives between 300 and 500 mm, reason for which the net hidrográfica is very poor, and it is formed by basins arreicas and endorreicas, since the rivers of scarce summery flow usually get lost for infiltration when arriving to the plains. The oriental part of the Cordovan mountains only has more developed rivers that have been regulated with preys for its hydroelectric use and for the watering. 
The valleys of Catamarca and Chili and Aimogasta, in The Rioja, they are areas where he/she combines the cultivation (vine, olive tree, corn, etc.) and the breeding of having won ovino and caprino. The cities of San Fernando of the Valley of Catamarca and The Rioja highlight, both capitals of the counties to those that give name, located in plains surrounded by the mountains; their economic activities depend on the agriculture and the cattle raising.
LLANURA PLATENSE
The denominated Llanura Platense is an immense plain. It is a sedimentary basin in fact, located in the northeast sector of the emerged American Argentinean territory that he/she understands a complex net hidrográfica. On the other hand, analyzing the structure morfoestructural of the Llanura Platense the evident resemblance is observed that exists between this plain and those of the Orinico and that of the Amazons; he/she shows that the Llanura Platense is an excellent element inside the combined morfológico subcontinental and continental American. 
This region is defined the N by the rivers Pilcomayo, Paraguay and High Paraná; to the S for the river Colorado; to the AND for the rivers Aguapey and Uruguay, the River of the Silver and the ocean South Atlantic; to the OR the Plain pretty Platense with the estribaciones of the system western orográfico. In spite of constituting an enormous region morfoestructural, the Llanura Platense understands important subregiones like the chaco, The Pampas, the tidelands correnttinos, the lomadas entrerrianas and the deltaic plain, each one of which it presents marked geographical peculiarities. 
The Llanura Platense contains total or partially eleven counties, among them the three more populated of the country (Santa Faith, Córdoba and Buenos Aires). In its territory it is also located the city of Buenos Aires, capital and center neurálgico of the country, and the main Argentinean urban masses are summoned (the Great Buenos Aires, The Silver, Santa Faith and Rosario), in which he/she concentrates great part of the tertiary activity and most of the industrial production is obtained.
MESETA SUBTROPICAL
            Located in the northeast end of the Argentina, the Subtropical Plateau extends by way of wedge between Paraguay and Brazil, and it is partially defined by the rivers Iguazú, Paraná and Uruguay. A dominant element in the region is, therefore, the mighty rivers as concecuencia of the climate sibtropical without dry station (with precipitations between 1 200 mm and 1800 mm). Physically, the region is characterized by the plateau of Missions, a block covered with gritty and volcanic rocks that it is raised. The tributaries of the Paraná and the Uruguay have erosionado the borders of the plateau, giving him an arched form. The forest and the cultivations sutropicales (tea, dull tung,yerba), for which he/she has been practiced the it touches, they are the most characteristic landscapes. 
The area has suffered, likewise, the embates of a limitless deforestation, that which, next to the already the man's mentioned action, it has caused serious environmental concecuencias. The cattle raising is developed mainly in the bordering area between the counties of Missions and Currents, highlighting the breeding of Creole species and cebú mestizos. The main city of the Subtropical Plateau is Posed, where they concentrate the tertiary activities of the region.
CUYO
            In the piedemonte of you Walk them Central, the rivers cordilleranos San Juan, Mendoza, Tunuyán, Diamond and Atuel that belong to the basin endorreica of the Desagüadero or Salted, they give life to one of the most arid regions in the Argentina: the region of Whose. With temperatures that oscillate between the 10º and the 22ºC, but much more variable among day and night, and inferior precipitations to 300 mm, the oasis cuyanos is the result of the tenasidad of the human action. 
The grown ones eventual of the rivers, fed exclusively by eldeshielo cordillerano, they have been regulated with preys that allow their hydroelectric use and for the watering of the fertile lands cuyanas. Another important resource of the region is the exploitation of petroleum in the county of Mendoza, as well as of natural gas. The main cities of the region are San Juan and Mendoza. This last form a great urban mass with the cities of their immediate environment.
NOROESTE
            The puna is an extensive highland, located in the heart of America of the S that exceeds the Argentinean limits, also occupying NOT the of Chile, the SO of Bolivia and the S of Peru. He/she rises to more than 4 000 m of height and it remains isolated by high outlying mountains. Extremely arid (less than 300 mm of precipitation), thermal oscillations can take place in her of up to 40ºC between the day and the noche.  
The rivers are scarce and seasonal, for what is a desert of height in fact. The three gulches of Humahuaca, of the Bull and of the Valles Calchaquíes, to those that gulches converge of smaller, they get off the puna and they allow their access. Although the climate of the gulches is also arid, it presents less rigurosidad than that of the puna. These three big gulches end in wide valleys (Jujuy, Lerma), where they are the big cities of NOT and an important agricultural activity is made. The main urban nuclei are San Miguel of Tucumán, it Jumps and San Salvador of Jujuy.
MAR ARGENTINO
            The oceanic masses, the marine or oceanic funds and the islands that emerge of the marine funds, as well as the group of the coast of the country, they constitute the region geographical denominated Argentinean Sea globally. Said otherwise, the Argentinean Sea is the aceáno portion that is located on the Argentinean continental platform (approximately 1 000 000 km2), for what this geographical concept is not comparable to the normative ones juridical that specify the Area Economic Sole right (2 000 000km2) .  
The Argentinean Sea is crossed by a cold current coming from the Pácifico, that of the end of Ovens that forks to the height of the archipelago of the Earth of the Fire, and a warm one that, coming from the Brazil, it contributes moderated waters and of high salinity. The geomorphology of the Argentinean platform is very similar to that of the Patagonia, that is to say he/she understands plateaus that escalonadamente descends toward the AND, crossed in occasions by tectonic depressions or fence that constitute the continuation of the rivers patagónicos. 
The Argentinean Sea presents, likewise, a rich and invaluable patrimony marine faunístico. The plankton, very abundant, and the algae and the small crustaceans are, next to the anchovy and the sardine, the base of the alimentary chain. Other bigger fish are plentiful as the hake, the beautiful one or the mackerel, and also birds (gulls, seabird, penguins, cormoranes). they also Highlight the marine mammals, marine wolves and marine elephants, dolphins and orcas. Some of these species, as the marine wolf of two hair that was almost exterminated in the XIX century due to the value of their skin, they are in extinction danger due to the environmental aggression (as, for example, the pollution caused by the oil prospectings) that all human activity behaves.

PATAGONIA
            The region patagónica, located the S of the river Colorado, is divided in the Andean, mountainous, humid Patagonia (with abundant glaciers, lakes and covered with vegetation boscosa), and the patagonia extraandina that enjoys a cold and dry climate, and it is characterized by a group of plateaus, cut by fluvial valleys that are projected in way staggered toward the Atlantic, constituting high cliffs on the coast, of until 100 m of height. An important economic activity of the region is the breeding of having won ovino, although it is also significant the breeding of bovine livestock and the vine cultivation and fruit-bearing. 
The main wealth is, however, the exploitation of petroleum, activity that determines the economic and demographic development of the urban concentrations of the region, as Comodoro Rivadavia and Neuquén. The coast patagónica is not very favorable for the installation of ports, due to the scarce articulation that the geography imposes to the coastal cliffs and the great width of the tides that can reach several meters. For that reason, the cities are usually summoned in the deep estuaries of rivers, as Viedma, Rawson (been founded by Welsh immigrants), Wanted Port, Port Santa Cruz and Galician River, or in sheltered gulves as San Antonio Oeste and Puerto Madryn. To the S of the Big island of Earth of the Fire, on the channel Beagle, is the city of Ushuaia, capital of the county of Earth of the Fire. In full mountain range and beside the lake Nahuel Huapi San Carlos from Bariloche, an international station of winter sports runs off with.
ANTÁRTIDA ARGENTINA
            Their surface is covered for an enormous mass of ice that can reach more than 2 000 m of thickness and of the one that the picks of more elevation only stand out. The climate, of polar type, is extremely rigorous (the temperatures summer stockings hardly surpass the 0ºC in the north of the peninsula Antarctica), fact that impedes all superior form of vegetation. In fact, in this petrified world, desértico, terribly cold and sweeping constantly for the wind there is little place for the life. The vegetation is represented by algae, mosses and líquenes, and the fauna by seals, whales and birds. It is plentiful, also, a small crustacean, the krill that is the base of the food of the cetaceans and he/she has a great economic importance as marine resource. At the present time a significant potential resource of krill exists, of which you/they are carried out important captures. It is, however, to be wise and to regulate the exploitation of this crustacean, since it plays an essential part in the feeding of other animals, among them the whales, for what an extraction desmesurada of the same one could cause disastrous effects on the antarctic ecosystem.
