What is the troposphere?
The Earth's atmosphere is divided into four layers, which are partially based on height, but are also categorized according to temperature. The bottom layer, or which is closest to the Earth, is called troposphere. Other layers of the troposphere are the stratosphere, mesosphere and thermosphere. Some scientists include the fifth category called the exosphere. The lowest level of atmosphere has a significant impact on people constantly, because there is almost all the weather.
troposphere cannot be easily categorized according to height, as it may vary in its thickness and also changes in the thickness in various places. Another factor that can change the thickness of this layer is the latitude of a particular place. It can be said that this part of the atmosphere has approximately 7-8 miles in thickness (about 12 km), but is also generally shallower at the Earth's poles and the deepest near the equator.
In addition to being responsible to the weather, the troposphere also contains that the gases that help keep life on the ground. Unfortunately the density of this section nThe decreased atmosphere and layers that push it also maintain many undesirable circulating gases, including various greenhouse gases. These can have the overall effect on the weather and also on the heat of the air. In general, however, as the troposphere rises to height, its temperature decreases.
When people look at pictures or graphical representation of an atmosphere layer, they may still seem, creating a false idea that these layers are not active. Unlike static photographs or illustrations in scientific books, people should think of this layer of atmosphere as very active. It constantly circulates air and in many ways interacts with the ground. It is in a constant flow because it responds to the ground temperature, the pressure of the above layers and the light of the sun and produces winds, clouds, fog, storm and sunny weather.
Another important fact that people should realize about the troposphere is that it is directly under the stratosphere.In fact, the thin layer called tropopause separates. However, most people would usually know the stratosphere as an area containing an ozone layer.
As well as the troposphere, the ozone layer is also the thinnest on the poles, and the gases from this lowest layer affect the degree in which the ozone layer works, and even creates holes that cannot protect people from the harmful rays of the sun. It should also be considered an interactive process. When people fill the troposphere by harmful gases or pollutants, some of which are filtered and destroyed or destroyed or the thin part of the ozone layer, creating less protection for all.
