Question

write briefly about layers of the atmosphere​

Answer 1

Answer:

The atmosphere can be divided into layers based on its temperature, as shown in the figure below. These layers are the troposphere, the stratosphere, the mesosphere and the thermosphere. A further region, beginning about 500 km above the Earth's surface, is called the exosphere.

There are 5 layers of atmosphere.

• Troposphere
• Stratosphere
• mesosphere
• thermosphere
• Exosphere

____________________

$\huge \text{Troposphere}$

Troposphere is the most important layer of atmosphere. the air we breathe exists here. almost all the weather phenomena like rainfall, fog and hailstorm occur in this layer.

$\huge \text{Stratosphere}$

Stratosphere is free from clouds and associated weather phenomena, making conditions most ideal for flying aeroplanes. one important feature of Stratosphere is that it contains a layer of ozone gas which protects us from harmful sun rays.

$\huge \text{mesosphere}$

mesosphere is the third layer of the atmosphere. meteorites burn up in this layer on entering from space.

$\huge \text{thermosphere}$

in thermosphere, the temperature rises rapidly with increasing height. this layer helps in radio transmission. in fact, radio waves transmitted from the earth are reflected back to the Earth by this layer.

$\huge \text{Exosphere}$

the upper most layer of the atmosphere is known as Exosphere. this layer has very thin air. light gases like helium and hydrogen float into the space from here.
