Before entering fully into the definition of the term troposphere, it is necessary to proceed to discover its etymological origin. In this sense, it must be emphasized that it derives from Greek, since it is the result of the sum of two nouns:
-The word “tropes”, which can be translated as “turn”.
-The noun “sphaira”, which is synonymous with “sphere”.

The troposphere, a term that can also be used with accent in the AND (and therefore without accent), is the atmospheric layer which is located closer of our planet. It is, therefore, the lower atmospheric zone in terms of its altitude.

TroposphereWith between seven and twenty kilometers thick according to the region of the Land, the troposphere is the thinnest layer (with less thickness). However, it houses all those meteorological phenomena that affect life on the planet. Rain and winds, for example, originate in this layer of the atmosphere which, on the other hand, has the highest concentration of water vapor and oxygen.

In the troposphere, moreover, the planes, the helicopters and the rest of the conventional aircraft that usually carry passengers. Space shuttles, on the other hand, reach higher layers.

Due to its characteristics, the troposphere regulates terrestrial temperature. In the absence of this atmospheric layer, the thermal variability on Earth would be very wide and life would not be possible. It should be noted that, from two kilometers in height, the temperature descends a few 6.5 degrees centigrade for every thousand meters.

Above the troposphere there is a transition zone called tropopause. This space is the upper limit of this cap of the atmosphere. After the tropopause, the stratosphere. In this way it can be said that the next layer of the troposphere is the stratosphere, although both are separated by the tropopause.

In addition to all the above, we have to highlight another series of interesting data about the troposphere, among which are the following:
-The boundary layer is what its internal part is called.
-In places of the aforementioned boundary layer where there are smooth surfaces, the usual thing is that there are fluid winds, while, in areas with mountains and mountain ranges, the winds are much more mixed.
-What is the height of the tropopause depends on several factors, such as the time of day that it is, the season of the year in which it is or the latitude that exists.
-When it approaches the equator, the tropopause is about 20 kilometers above sea level. However, in the winter months, for example, the mentioned tropopause is lower.

We cannot ignore either that there is a web space called that was launched in 2005 and that revolves around what is air pollution and air quality. In this way, it seeks to make the population aware of the need to bet on ensuring the environment, both for it and for the human being’s own health.
