discuss the different layer of atmosphere
Answers
________________
1) Troposphere:
✔️This is the lowest atmospheric layer and is about seven miles (11 km) thick. Most clouds and weather are found in the troposphere. The troposphere is thinner at the poles (averaging about 8km thick) and thicker at the equator (averaging about 16km thick). The temperature decreases with altitude.
2) Stratosphere:
✔️The stratosphere is found from about 7 to 30 miles (11-48 kilometers) above the Earth’s surface. In this region of the atmosphere is the ozone layer, which absorbs most of the harmful ultraviolet radiation from the Sun. The temperature increases slightly with altitude in the stratosphere. The highest temperature in this region is about 32 degrees Fahrenheit or 0 degrees Celsius.
3) Mesosphere:
✔️The mesosphere is above the stratosphere. Here the atmosphere is very rarefied, that is, thin, and the temperature is decreasing with altitude, about –130 Fahrenheit (-90 Celsius) at the top.
4) Thermosphere:
✔️The thermosphere starts at about 55 kilometers. The temperature is quite hot; here temperature is not measured using a thermometer, but by looking at the motion and speed of the rarefied gases in this region, which are very energetic but would not affect a thermometer. Temperatures in this region may be as high as thousands of degrees.
5) Exosphere:
✔️The exosphere is the region beyond the thermosphere.
6) Ionosphere:
✔️The ionosphere overlaps the other atmospheric layers, from above the Earth. The air is ionized by the Sun’s ultraviolet light. These ionized layers affect the transmittance and reflectance of radio waves. Different ionosphere layers are the D, E (Heaviside-Kennelly), and F (Appleton) regions.

Atmosphere and its different layers.
Atmosphere is also considered as life of a Human beings. So many atmosphere layers are present on the Earth upper side.
Because of having atmosphere, humans can breathe and oxygen is transferred from one place to another. We refer word Atmosphere in various languages. As well as, Atmospere words means Nature and Environment in short words.
The atmosphere is divided into consisted of various layers which are called as 'Layers of Atmosphere'. The layers of atmosphere are dependent or formed because of their temperature.
- Troposphere, stratosphere, mesosphere and thermosphere are the four main layers of atmosphere.
1) Troposphere:-
Troposphere is the first layer of Atmosphere and it is also the lowest layer of the atmosphere. Troposphere is the layer in which we live. As well as, the Clouds and weather is the part of Troposphere.
=> Layer is present on the 7 to 8 km from surface of earth.
=> Highest point - 17 - 18 km
=> Air consists of - 75%
2) Stratosphere:-
Stratosphere is the layer which starts from the 10th or 11th km from the surface of earth. This layer is mainly consists of very less things. The Ozone layer is present in this Stratosphere.
=> Temperature = -45℃
=> Layer present = 30 to 40 km
=> Air proportion = 7 to 10%
3) Mesosphere:-
This is the layer which is present above the 70km from the surface of earth. The temperature of this layer is very less because of very high height. In this region, There are very high rays of Sun.
=> Temperature = -90℃
=> Layer present = Above 70 Km
=> Air proportion = 4 to 5 %
4) Thermosphere and Ionosphere:-
Thermosphere and Ionosphere are the last layers of atmosphere. They are present at very high layer or region of atmosphere. Thermosphere and Ionosphere have very high temperature because of Height.
=> Layer present = Above 80km
=> Air proportion = 2 to 3%
=> Temperature = More than -95℃
Exosphere
The region above about 500 km is called the exosphere. Exosphere consists Oxygen, Hydrogen and gases which are present on our earth in very less proportion. It has magnetic fields in very large proportion, Because of which, It is also called as magnetosphere.
