natural areas of the Earth for the first time allocated Dokuchaev in 1898.Scientists believe that the living conditions (including climate, water, relief), as well as the flora and fauna in a particular area of the planet is closely linked.That is why they must be studied as a whole, paying attention to the mutual influence.Dokuchaev first formulated the law of geographical zoning.
Today it is believed that the natural area - this complex with its own landscape, which is formed under the influence of climate and of the distribution of moisture and heat.In addition, this type of area is characterized by its own flora, unique wildlife, and soil type.
Interestingly, the climatic zones of the world, and natural areas are closely linked, since it is influenced by the external environment form the corresponding conditions for the existence of living organisms.
equatorial forests are characterized by humid and hot climate.Territories located mainly in the Amazon (South America), as well as in Africa, on either side of the Congo River.This natural area is also present in the territory of Australia and some islands of Oceania.
equatorial forests are characterized by diverse vegetation and abundant wildlife.The high rainfall and a constant warm temperature creates the ideal conditions for the formation of the jungle.The trees are home to a lot of interesting animals, including monkeys, sloths, flying foxes.Diverse and world of birds - you can see several species of parrots, birds of paradise and hummingbirds.By the way, in the territory of the equatorial forest is found the world's largest snake - anaconda.
the alternating humid forests - the natural areas of the Earth, which are characterized by seasonal weather changes.It generates heat, damp and cool periods.In most cases, these forests are located in the tropical climate zone.
temperate forests - occupies a large part of North America and Eurasia.There is clearly highlighted one-year seasonal weather, which is typical for a temperate climate.Forests can be both deciduous and mixed.The most typical plants of this area are the following: maple, oak, birch and linden.As for fauna, it is in these areas inhabited by bears, wolves, moose, lynx, sable and marten sometimes.
Savannah - natural areas of the Earth, which are located in tropical, sub-tropical and sub-equatorial climate zone.They occupy vast territories in Africa, Australia, Central and South America.The vegetation consists mainly of handicraft or grassy forms - from the trees you can see only baobab, acacia and eucalyptus.Typical animals are considered to be zebras, giraffes, elephants and ostriches.
Steppe characterized by a dry climate and minimal rainfall.That is why it is only inhabited by the representatives of herbaceous flora.In the American prairies are found Lama, coyotes, jaguars, armadillos and bison.As for the Eurasian steppes, the situation is a bit different - the fauna is represented mainly by rodents.
Desert are located in different climatic zones.The only common feature is considered to be a meager amount of annual rainfall and a large range of temperatures (eg, daytime temperatures can be 40 degrees, and at night only 15).Accordingly, the flora and fauna is not as rich.On the territory of the desert inhabited by only those organisms that have adapted to withstand a long time without water and food.
polar desert - another interesting area, which is also characterized by minimal rainfall.Such areas are located near the Arctic Circle.Interestingly, almost half a year here prevails day and the next six months - an impenetrable night.The most characteristic fauna - a polar bear, seals, penguins.
As can be seen, the natural areas of the Earth are very different from each other.Each of them has its own unique characteristics.
