Ozone Layer Depletion
The atmosphere can be divided into five layers according to the diversity of temperature and density. They are:-
- Thermosphere (Ionosphere)
Troposphere - The lowest part of the Earth's atmosphere is referred to as the troposphere. The troposphere rises from the Earth's surface to a height of 7 to 20 kilometers. Within this stratum, all weather occurs. Every 165 meters in height results in a 1 degree Celsius drop in temperature. The stratosphere and troposphere are separated by the tropopause.
Stratosphere - The second layer of the atmosphere, located above the troposphere, is known as the stratosphere. It rises to a height of 50 kilometers. The fact that this layer is above stormy weather and contains strong, consistent horizontal winds gives it some advantages for flight. This layer contains the ozone layer. The ozone layer shields the planet from dangerous radiation by absorbing UV rays. The mesosphere and stratosphere are separated by the stratopause.
Mesosphere - Located above the stratosphere, the mesosphere. It is the layer of the atmosphere that is the coldest. Starting at 50 km above the Earth's surface and rising to 85 km is the mesosphere. It hits -100 degrees Celsius after 80 kilometers. In this layer, meteors burn up. Mesopause, which divides the mesosphere and thermosphere, is the term for the top limit.
Thermosphere - This layer is located 80 to 400 km above the mesopause. This layer reflects radio waves that are emitted from the Earth. Height leads to an increase in temperature. This layer contains satellites and the aurora.
Exosphere - The exosphere is the atmosphere's topmost layer. Exosphere refers to the region where atoms and molecules can escape into space. It starts from the top.
Ozone layer depletion is a major phenomenon in, Troposphere, Stratosphere, Thermosphere, Exosphere
In the stratosphere, ozone layer depletion is a significant phenomenon. Depletion of the ozone layer is simply the wearing down (decrease) of the ozone content of the stratosphere.
