The atmosphere are often divide into layers support its temperature, as shown within the figure below. These layers area unit troposphere layer and thermostat. Another region, that starts five hundred kick on top of the Earth's surface, is name the exhibition.
The line on the figure below shows however the temperature varies with the altitude (temperature scale is given below the diagram). The dimensions on the proper shows the pressure as an example, there's just one thousand of the pressure on the bottom.

The layers of atmosphere are as follow:
Troposphere
It's the smallest half of setting - the part we have a tendency to board. This includes most of our seasons i.e. clouds, rain, snow. The temperature during this a part of the atmosphere cools because the distance on top of the world will increase by five years per metric linear unit. the particular amendment in temperature depends on the weather.
The troposphere consists of concerning seventy fifth air, and most vapor (which forms clouds and rain). The decrease in temperature with altitude is that the results of lower pressure. If the air parcel moves upwards, it moves (due to low pressure). Once the air expands, it cools. therefore the air is cool downward.
The lower a part of the layer is name the physical phenomenon. From here, the movement of air is set by the characteristics of the Earth's surface. This turbulence happens once air involves the surface of the world, and as before long because the earth is heat by the sun through thermals. It distributes heat and wetness within the turbulent layer, still as pollutants and different elements of the setting.
The higher a part of the layer is name the troposphere. It's the bottom of the poles, wherever it's concerning 7-10 points on top of the bottom. It's the longest close to the equator (approximately 17-18 km).
Stratosphere
It is concerning fifty Km from Tarp oz. It contains most of the gas within the atmosphere. The rise in temperature with altitude is because of the absorption of ultraviolet (UV) radiation from the sun by this gas. The temperature within the summer pole is more than the warmth pole and not up to the winter pole.
By gripping dangerous ultraviolet light radiation, the gas within the layer protects United States from carcinoma and different health harm. However, chemicals (called CFCs or fr-eons, and halon) that were once employ in refrigerators or spray cans and hearth extinguishers have reduce the number of gas, particularly in stratospheric matter. At the polar great circle, that causes the allege "Antarctic gas Hole".
Humans have currently stop creating the foremost harmful CFCs. we have a tendency to expect the hole to recover within the twenty first century, however it is a slow method.
Mesopotamia
The region on top of the layer is name the layer Mesopotamia. Here once more the temperature drops with altitude, and reaches a minimum of 90 degrees stargazer at "Mesopotamia".
Temperatures area unit on top of geographic area, and this is often the region wherever temperatures rise once more with altitude. This increase in temperature is because of the absorption of energetic ultraviolet and X-ray radiation from the sun.
The region of the atmosphere on top of eighty km is additionally cause by "ion spare", as a result of the energetic radiation pushes the electrons out of the molecules and atoms and converts them into "ions" with a charge. Temperatures vary between night and day and seasons, like the amount of ions and electrons. The particle spare radio reflects and absorbs waves, permitting United States to receive shortwave radio broadcasts from different components of the planet to New island.
