What is the Meaning & Definition of Tundra
He is designated with the term of Tundra to open and flat land, subglacial climate and subsurface ice cream, lacking of arboreal vegetation, mostly with the covered ground lichens and mosses and in many places swampy.
The tundra is extended primarily by the northern hemisphere, more precisely in Siberia, Alaska, Northern Canada, South of Greenland and the Arctic coast of Europe. Meanwhile, in the southern hemisphere tundra is presented with much more even temperatures throughout the year and in areas such as the southern tip of Chile and Argentina, the sub-Antarctic islands like South Georgia and Kerguelen and in some small areas of the North of Antarctica that are close to the sea level.
With respect to its expansion in all the land, tundra specifically occupies one-fifth of emerged Earth surface and climbing latitudes (between 45 ° and 60 °) to both antipodales poles begin the mentioned areas of tundra and because lowering the above-mentioned latitudes are coniferous forests with some dwarf Birch in the northern hemisphere and in the South with forests and Rainforest cold followed by conifers southern boreal anti.
Also, there are biomes similar to which presents the tundra by the effect of the height, as in Tibet, or some of the tropics of Peru and Bolivia.
There are two types of tundra, the Alpine and the Arctic. To the Alpine it it can be found in point mountainous areas and the second in areas lower where puddles are formed and it is precisely this combination in which the vegetation will abound.
With respect to the type of climate that prevails in this type of terrain, we find winters severely cold and fresh, and very short summers with light rains during the summer and some frost. During the winter the temperature not normally exceed 0° and terrain is covered by ice and snow, meanwhile, in the summer, temperature will vary from 0° to 10° and part of the land becomes swamps due to melting and that soils do not allow the water to drain.
Flora that it prevails, we said, were mosses, lichens and grasses and wildlife with respect, they are polar bears, reindeer, Arctic fox, among others.
