Atmosphere
Our earth is surrounded on all sides by a thick layer of air, which is called the atmosphere. all living things on earth The atmosphere plays an important role.
Structure of the atmosphere
Our atmosphere is divided into five layers, which cover the surface of the earth.
starts from These are –
1. Troposphere
2. Stratosphere
3. Mesosphere
4. Thermosphere
5. Exosphere
1. Troposphere
This pitta is the most important pitta of the atmosphere. Its average height is 13 is kilometer. We breathe the air present in this circle. of weather Almost all the phenomena such as rain, fog, thunderstorms and hailstorms occur within this layer.
2. Stratosphere
The part above the troposphere is called the stratosphere. It extends up to the high Chai range of about 50 km. This bile is almost free from clouds and meteorological phenomena. As a result, the conditions here There are ideals for flying a plane. One important feature of the stratosphere is that it contains ozone gas. This layer protects us from the harmful gases coming from the sun.
3. Mesosphere
This is the third layer of the atmosphere. It is just above the stratosphere. It reaches a height of about 80 km. Has spread. Meteorites that enter from space get burnt when they come in this layer.
4. Thermosphere
The temperature in the outer atmosphere increases very rapidly with increasing altitude. ion market a part of this pit. It extends from 80 to 400 kms. This port is used for radio communication It happens. In fact, the radio waves transmitted from the earth are reflected back on the earth by this layer.
5. Exosphere
The uppermost layer of the atmosphere is known as the Exosphere. It is the first layer of air. light gases For example, Helium and Hydrogen float in space from here.
