Atmosphere of Earth

 

I hope all the readers are doing well, before that we know that scientists have divided the earth into four main layers based on the different places of the earth and the different characteristics of these places.

And those are the four basic layers

The lithosphere

 

Hydrosphere

Biosphere

And the atmosphere.

If anyone wants links to this post then comment,

Today we will learn more about atmosphere,

Our atmosphere surrounds our earth from all sides be it north, south or east or west.

Our atmosphere is divided by scientists into different zones based on their changing temperature,

Atmospheric pressure at the surface of the Earth is atm.

And this pressure decreases as you rise above the surface of the earth.

Scientists divide the atmosphere into the following four zones,

The troposphere

The stratosphere

Mesosphere and Thermosphere

Today we will learn about only one zone,

Troposphere.

It is the first layer of the atmosphere which is very close to the earth's surface.

Its condition is always changing and we live in the same zone.

The height of this zone is up to eleven kilometers from the ground.

Altitude weather and pressure depends on its height.

Almost all dust particles and water droplets are present in this layer Snow, rain, cloud formation, all these are formed here.

70 to 75 percent of atmospheric gases are present in this zone

It contains mostly nitrogen and oxygen followed by carbon dioxide and water droplets.

The air in this zone is warmer than the rest of the zone because it is connected to the surface of the earth, its warm air (gas) rises to the top, so cold air comes here and takes its place.

Its temperature varies from 15°C near the surface to minus 56°C at high altitudes.
