The Atmosphere and Sunlight

The Atmosphere and Sunlight

The Atmosphere: - The air cover around the Earth is called the atmosphere .The atmosphere is associated with the Earth due to gravity.

Atmosphere alongside the Earth also revolves around the atmosphere.

The upper limit of the atmosphere is approximately 10000 kilometers.

There is a reservoir of many gases in the atmosphere. There is a certain proportion of the different gas in the atmosphere.

Nitrogen is at 78% of the atmospheres. Oxygen at 21% and carbon dioxide in the remaining 1% hydrogen and ozone.

There are dust particles and water vapor in the ground due to which rain and snow are caused.

The amount of water vapor in the atmosphere varies from place to place and from time to time.

Atmosphere structure - The atmosphere is surrounded by many sheets or layers. Along with the height, changes in the temperature

On these basis, the following four layers of the atmosphere are formed.

  1. Troposphere - It is the lowest layer of the atmosphere. Along with the weather The Troposphere is the thickest layer of the atmosphere. Water vapor and dust are also more in it.

 2. Stratosphere - The height of the stratosphere is approximately 50 kilometers.Altitude increases heightitude in the stratosphere Due to the presence of ozone gas in the panic system, heat is increased. Ozone absorbs disturbed harmful ultraviolet rays from the Sun. There is no change in the stratosphere in the stratosphere. Therefore, it is considered to be the best for such aerial flights.

3. Mesosphere - Mesosphere comes after stratosphere. It extends from 50 kilometers to 90 kilometers. In this division, the temperature decreases along with altitude.

4. Ionosphere - The significance of this division is specifically from the point of view of the radio society, because the same electricity on the earth reflects the electricity driven waves of the radio.


Sunlight - The light of the earth is obtained from the Sun. Sun is very hot, which distributes heat in large amounts in all directions. Only a very small part of the sun

Only 51% of the light 35 percent of the 49 percent sun-propelled clouds are reflected by the oceans and plains and then they go back in space.

The remaining part is absorbed by the water vapor and dust particles present in the atmosphere.


Atmospheric pressure -
                        Weight in the air The weight of the air column on the ocean floor is high and the height decreases along with it.

Air pressure is measured in the given time. Air pollution is different from place to place on Earth

Air goes towards lower cost area than high pressure area.

Variation in air pressure is due to the atmospheric temperature of the atmosphere.
