Question

The most important layer of atmosphere is ________.
A.Troposphere
B.Thermosphere
C.Mesosphere
D.None of these

Answer 1

Hint: The surface of the earth is called tropical to the layer or lower at the bottom of the environment. The average thickness of this layer is approximately 14 km. Most weather making incidents occur in this layer. The importance of this layer is very important to the Earth. This is the most important layer of the environment.

Complete answer: Although the structure of the environment extends about 10,000 km. Access the height, but the 99% atmosphere is only 32 km. Is limited to. The atmosphere can be viewed by dividing into 5 different rooms.

-Troposphere: It is 8 km away on the poles. And 18 km height has been found on the toxic line. In this division, the temperature of 1 degree Celsius decreases at a height of 165 meters and height of each km. Decreases at 6.5 ° C at the height of temperature. This is the only normal heat decline rate. The passive defaults are called. All seasonal activities occurring in the environment. Work is found only on the board. The highly intense winds are called Jet Pawan (Jet Stream).

-Stratosphere: At the beginning of this division, the temperature is stable, but 20 km. After height, the temperature starts suddenly. This is due to the presence of ozone gases, which absorbs ultraviolet rays and promotes temperature. This division is free from seasonal light, so the aircraft like to fly the plane here.

-Mesosphere: The height of this division is 50 to 80 km. It depends on. There has been a decline in temperature. The temperature reaches 100 degrees Celsius on the middle limit which is the minimum temperature of the atmosphere.

-Ionosphere - Its height is 80-640 km. It has excessive amounts of existing particles and starts with temperature height. Radio waves of different frequencies are reflected by the same layer of the environment. The ionosphere has broken into several layers.

-Exosphere: Its height is 640-1,000 km. It also has the preponderance of existing charged particles and there are separate layers of N., O, He, H, respectively. 1,000 km in this division. After this the atmosphere becomes very sparse and eventually 10,000 km. After the elevation it gradually merges into space.


So option A is the correct answer.

Note: The atmosphere is called the wide repository of air around the earth. It allows short waves of solar radiation to reach the surface of the Earth, but becomes a barrier to long waves of earthly radiation. In this way, it acts like a giant 'glass house' by stopping the heat, thereby maintaining an average temperature of 15 ° C on Earth. This temperature is the basis of the development of the biosphere on Earth.
