How is our atmosphere formed? (Atmosphere in hindi), structure of the atmosphere, interesting information related to the atmosphere

Atmosphere in hindi-Have you ever thought. Why our earth is different from other planets, why life is possible only on earth. Our answer to all these questions Atmosphere I am hidden. Our Atmosphere Due to the very complex and mysterious texture it creates such an environment. that suits life. Friends, in this article today we Atmosphere Will know about

What is Atmosphere – What is Atmosphere in Hindi

The wide spread of air that surrounds the earth is called atmosphere. The study of the upper layer of the atmosphere is called aerology and the study of the lower layer is called meteorology.

By volume, the mixture of different gases in the atmosphere (within thirty miles) is as follows – Nitrogen 78.07%, Oxygen 20.93%, Carbon-di-oxide .03% and Argon .93%.

Some important gases found in the atmosphere – Atmosphere meaning in hindi


The percentage of this gas is greater than that of all gases. nitrogen Due to the presence of air pressure, the power of the winds and the reflection of light are felt. This gas has no colour, smell or taste. This is the biggest advantage of nitrogen.

that it protects the objects from burning rapidly. If there was no nitrogen in the atmosphere, it would be difficult to control the fire. Nitrogen is used to make proteins in plants, which is the main component of food. This gas extends up to a height of 128 km in the atmosphere.


It works with other substances to burn. oxygen Without it we cannot burn fuel. Hence it is the main source of energy. This gas is spread up to an altitude of 64 km in the atmosphere, but its quantity decreases very much after going above 16 km.

carbon dioxide

It is the heaviest gas and due to this it is found in the lowest layer, yet it extends up to a height of 32 km. This gas is permeable to the radiation coming from the sun and impermeable to the radiation reflected from the earth.

so it Green house is responsible for the impact and keeps the lower layer of the atmosphere warm.


This gas is a special form of oxygen. It is found in the atmosphere in very small quantities only at high altitudes. It absorbs some part of the strong ultraviolet radiation coming from the Sun. It is concentrated at an altitude of 10 to 50 km.

Due to the decrease in the amount of ozone gas in the atmosphere, ultraviolet radiation of the sun can reach the earth in large quantities and spread terrible diseases like cancer.

In addition to gases, water vapor and dust particles are also present in the atmosphere. The blue color of the sky is visible only due to dust particles.

Water vapor absorbs some of the insolation coming from the Sun and stores the heat radiated by the Earth. Thus it acts as a blanket, so that the earth can neither become too hot nor too cold. Rain is caused by the condensation of water vapor.

Water vapor is the most variable and unevenly distributed gas in the atmosphere. Responsible for maintaining the earth’s temperature is—CO, and water vapor.

Composition of Atmosphere – Layers of Atmosphere in Hindi

The atmosphere is divided into the following layers-

  1. Troposphere
  2. Stratosphere
  3. Ozonosphere
  4. Ionosphere
  5. Exosphere (hindi in Hindi)


It is the lowest layer of the atmosphere.
→ Its height is 8 km at the poles and about 18 km at the equator.
The rate of decline of temperature in the troposphere is 1°C per 165 m altitude or 6.4°C per 1 km altitude.

All the major atmospheric phenomena such as clouds, storms and rain occur in this circle. This zone is called the convection zone, because the convection currents are limited to the boundary of this circle. This circle is also called sub-mandala.


The stratosphere ranges from 18 to 32 km in height. The temperature remains the same. It includes weather events such as thunderstorms, thunderstorms, lightning, dust particles and water vapor.
etc nothing happens.

→ Ideal condition for flying aircraft is found in this circle.

The thickness of the stratosphere is greatest at the poles, sometimes disappearing at the equator.
Sometimes special types of clouds are formed in this circle, which are called mother of pearl cloud.


The ozone layer lies between 32 km to 60 km from the surface.
A layer of ozone gas is found in this system, which absorbs the ultraviolet rays coming from the Sun. That is why it is called the protective shield of the earth.
The gas that destroys the ozone layer is CFC (Chloro-fluoro-carbon), which is released from air conditioners, refrigerators, etc. Depletion in the ozone layer is caused by active chlorine (Cl) present in CFCs.
The Dabson unit is used to measure the thickness of the ozone layer.
The temperature in this circle increases with altitude; The temperature rises by 5°C per 1 km of altitude.


Its altitude varies from 60 km to 640 km. This part keeps getting ionized by low air pressure and ultraviolet rays.
In this circle, long radio waves are reflected from the D-layer at the bottom and short radio waves from the E,,E, and F,F2 layers. As a result of which the facility of radio, television, telephone and radar etc. is available on the earth. Communication satellites are located in this circle.


Exosphere The part above 640 km is called exosphere.

There is no upper limit for this.
Hydrogen and helium gas predominate in this system.
