It has an average depth of , and a maximum depth of . - Los Glaciares National Park ("Glaciers National Park") is a federal protected area in Santa Cruz Province, Argentina. The park covers an area of , making it the largest national park in the country. Established on 11 May 1937, it houses a representative sample of the Magellanic Subpolar Forest and western Patagonian Steppe biodiversity in good state of conservation. In 1981 it was declared a World Heritage Site by UNESCO. - Tin is a chemical element with the symbolSn (for ) and atomic number50, is a post-transition metal in group 14 of the periodic table. It is obtained chiefly from the mineral cassiterite, which contains tin dioxide, SnO. Tin shows a chemical similarity to both of its neighbors in group 14, germanium and lead, and has two main oxidation states, +2 and the slightly more stable +4. Tin is the 49th most abundant element and has, with 10 stable isotopes, the largest number of stable isotopes in the periodic table, thanks to its magic number of protons. It has two main allotropes: at room temperature, the stable allotrope is -tin, a silvery-white, malleable metal, but at low temperatures it transforms into the less dense grey -tin, which has the diamond cubic structure. Metallic tin is not easily oxidized in air. - Brazil, officially the Federative Republic of Brazil, is the largest country in both South America and Latin America. As the world's fifth-largest country by both area and population, it is the largest country to have Portuguese as an official language and the only one in the Americas. Bounded by the Atlantic Ocean on the east, Brazil has a coastline of . It borders all other South American countries except Ecuador and Chile and covers 47.3% of the continent's land area. Its Amazon River basin includes a vast tropical forest, home to diverse wildlife, a variety of ecological systems, and extensive natural resources spanning numerous protected habitats. This unique environmental heritage makes Brazil one of 17 megadiverse countries, and is the subject of significant global interest and debate regarding deforestation and environmental protection. - Argentina, officially the Argentine Republic, is a federal republic in the southern half of South America. Sharing the bulk of the Southern Cone with its neighbor Chile to the west, the country is also bordered by Bolivia and Paraguay to the north, Brazil to the northeast, Uruguay and the South Atlantic Ocean to the east, and the Drake Passage to the south. With a mainland area of , Argentina is the eighth-largest country in the world, the second largest in Latin America, and the largest Spanish-speaking one. The country is subdivided into twenty-three provinces (singular "provincia") and one autonomous city ("ciudad autonoma"), Buenos Aires, which is the federal capital of the nation as decided by Congress. The provinces and the capital have their own constitutions, but exist under a federal system. - Biodiversity, a contraction of "biological diversity," generally refers to the variety and variability of life on Earth. One of the most widely used definitions defines it in terms of the variability within species, between species and between ecosystems. It is a measure of the variety of organisms present in different ecosystems. This can refer to genetic variation, ecosystem variation, or species variation (number of species) within an area, biome, or planet. Terrestrial biodiversity tends to be greater near the equator, which seems to be the result of the warm climate and high primary productivity. Biodiversity is not distributed evenly on Earth. It is richest in the tropics. Marine biodiversity tends to be highest along coasts in the Western Pacific, where sea surface temperature is highest and in the mid-latitudinal band in all oceans. There are latitudinal gradients in species diversity. Biodiversity generally tends to cluster in hotspots, and has been increasing through time, but will be likely to slow in the future. - South America is a continent located in the western hemisphere, mostly in the southern hemisphere, with a relatively small portion in the northern hemisphere. It is also considered a subcontinent of the Americas, which is the model used in nations that speak Romance languages. The reference to South America instead of other regions (like Latin America or the Southern Cone) has increased in the last decades due to changing geopolitical dynamics (in particular, the rise of Brazil). - Southern Cone is a geographic region composed of the southernmost areas of South America, south of and around the Tropic of Capricorn. Traditionally, it covers Argentina, Chile and Uruguay, bounded on the west by the Pacific Ocean, and south to the junction between the Pacific and Atlantic Oceans, which is the closest continental area of Antarctica (1000km). In terms of social and political geography, the Southern Cone comprises Argentina, Chile, Uruguay, Southern Brazil and sometimes Paraguay. - Santa Cruz River ( Spanish : Rio Santa Cruz ) is a river in the Argentine province of Santa Cruz . The Santa Cruz begins at the shore of the Viedma and Argentino Lakes , of glacial origin and located in the Los Glaciares National Park , and runs 385 kilometres ( 239 mi ) eastwards before reaching the Atlantic Coast , 350 kilometres ( 217 mi ) north of the southern tip of South America , creating a delta .
