Region It is a word that comes from Latin royal. It's about a territorial fragment which differs from the rest by certain particular characteristics, whether climatic, geographical, administrative or otherwise. natural , for its part, is that linked to the nature .
It is known as natural region , therefore, to the area whose delimitation is set by the physical geography . He territory which is considered as a natural region exhibits a certain uniformity in terms of its climatic conditions, its vegetation and its relief.
The boundaries of a natural region, ultimately, are set by the man arbitrarily In nature there are usually no exact limits: vegetation and weather conditions do not change from one meter to another, but gradually. Thus, delimiting a natural region ends up being a decision that the human being makes in a conventional way.
An example of a natural region is called Pampas region , which spans several provinces of Argentina , Uruguay and Brazil . It is a steppe with a temperate climate that, in general, lacks high elevations.
Just as the Pampas region is a natural region where the plain , exist natural plateau regions and natural mountain regions . In each case, the characteristics of the region and also the living beings that inhabit it vary. The animals who live in a mountain region are not the same as those who live on a plain or even on a plateau.
One type of natural region is the orographic , which is determined by the relief that predominates its surface. Within this group are the following types of natural region:
* mountain region : from the Himalayas, the Alps, the Andean region and the Himalayas, among others;
* plains region : Los Llanos (Colombia and Venezuela), Panonic Plain (Hungary), Grandes Llanos (North America) and La Pampa (Argentine Republic), to name a few examples;
* plateau region : Andean highlands, Mexican highlands, plateau of Tibet and Venezuelan Guiana, among others;
* hill region : the Midlands (England), The Ardennes (Belgium) and the Vosges (France), for example.
When the determinant of the boundaries of a region is the weather , talk about climatic region , although in this case the descriptions are not as precise as in the reliefs, since the parameters and terms used are less tangible, so to speak, and more arbitrary.
In order to describe a climate, it is possible to divide the planet into fringes, zones or latitude belts, which are drawn between each pole and the equator, and to understand them it is necessary to consider the circulation that takes place both in the troposphere (the lower atmosphere) and in the stratosphere (the upper atmosphere) of each of them. It is worth mentioning that phenomena of the latter were not known until the invention of certain technologies, such as artificial satellites, high-altitude flights and probe balloons.
On the other hand there is a type of natural region known as phytogeographic , which is mainly based on the preponderance of certain formations vegetables . The determination of a phytogeographic region is useful, for example, when planning the extension or improvement of these formations for exploitation in the economic field, and this occurs in the following cases: fire prevention, natural pasture areas , timber forests, etc.
The zoogeographic regions , meanwhile, are created paying attention to the distribution of animals mammals . In the geological period known as Triassic, which began more than 250 million years ago, the first mammals appeared, and after the disappearance of the dinosaurs they began to occupy their respective habitats and evolve. Its distribution is a more accurate reflection of geographical barriers than that of plants.
