Answer 2

Answer:

1'Troposphere

2,Stratosphere

3.Mesosphere

4.Thermosphere (Ionosphere)

5.Exosphere

Troposphere

;>It is the lowermost layer of the atmosphere.

>The height of this layer is about 18 km on the equator and 8 km on the poles.

>The thickness of the troposphere is greatest at the equator because heat us transported to great heights by strong convectional currents.

>Troposphere contains dust particles and water vapour      

Stratosphere

Stratosphere is found just above the troposphere.

It extends up to a height of 50 km.

The temperature remains almost the same in the lower part of this layer up to the height of 20 km. After this, the temperature increases slowly with the increase in the height. The temperature increases due to the presence of ozone gas in the upper part of this layer.

Mesosphere

It is the third layer of the atmosphere spreading over the stratosphere.

It extends up to a height of 80 km.

In this layer, the temperature starts decreasing with increasing altitude and reaches up to – 100 degree Celsius at the height of 80 km.

Meteors or falling stars occur in this layer.

Thermosphere

This layer is located between 80 and 400 km above the mesopause.

It contains electrically charged particles known as ions, and hence, it is known as the ionosphere.

Radio waves transmitted from the earth are reflected back to the earth by this layer and due to this, radio broadcasting has become possible.

Exosphere

The exosphere is the uppermost layer of the atmosphere.

Gases are very sparse in this sphere due to the lack of gravitational force. Therefore, the density of air is very less here.
