Question

what are the main layers of the atmosphere based on chemical composition of the gases? Write briefly about the characteristics of these layers.​

Answer 1

Answer:

Troposphere, stratosphere, mesosphere, thermosphere , exosphere

Explanation:

Troposphere:

This layer is the most important layer of the atmosphere .Its average height is 13km. The air we breathe exists here .

Almost all the weather phenomena like rainfall, fog and hailstorm occur in this layer.

Stratosphere :

Above the troposphere lies the stratosphere. It extends up to a height of 50 km. This layer is almost free from clouds and associated weather phenomenon, making conditions most ideal for flying aero planes. One important feature of stratosphere is that it contains a layer of ozone gas.

Answer 2

Answer: troposphere- lowest layer, more atmospheric disturbances, life supporting layer, clouds formation, temp decreases with height

stratosphere- ozone layer, aeroplanes fly , temp increases with height

ionosphere- radio waves reflect back from this, temp decreases with height

exosphere- topmost layer.
