HERE IS UR ANS

Explanation:
The structure of the atmosphere dictates the way the atmosphere behaves and controls how weather develops near the surface of the earth. The atmosphere consists of 4 layers: the troposphere, stratosphere, mesosphere, and thermosphere. ... This is the layer where we live and where weather happens......

Answer:
There are five layers in the structure of the atmosphere depending upon temperature. These layers are:
Troposphere
Stratosphere
Mesosphere
Thermosphere
Exosphere
.
Troposphere
It is considered as the lowest layer of Earth’s atmosphere.
The troposphere starts at the surface of the earth and goes up to a height of 7 to 20 km.
All-weather occurs within this layer.This layer has water vapor and mature particles.
Temperature decreases at the rate of 1 degree Celsius for every 165 m of height.
Tropopause separates
Troposphere and Stratosphere.
Stratosphere
It is the second layer of the atmosphere found above the troposphere.It extends up to 50 km of height
This layer is very dry as it contains little water vapour.
This layer provides some advantages for flight because it is above stormy weather and has steady, strong, horizontal winds.
The ozone layer is found in this layer.
The ozone layer absorbs UV rays and safeguards earth from harmful radiation.
Stratopause separates Stratosphere and Mesosphere
.Mesosphere
The Mesosphere is found above the stratosphere.
It is the coldest of the atmospheric layers.
The mesosphere starts at 50 km above the surface of Earth and goes up to 85 km.
The temperature drops with altitude in this layer.By 80 km it reaches -100 degrees Celsius.
Meteors burn up in this layer.The upper limit is called Mesopause which separates Mesosphere and Thermosphere.
Thermosphere
This layer is found above Mesopause from 80 to 400 km
.Radio waves that are transmitted from the earth are reflected by this layer.
The temperature increases with height
.Aurora and satellites occur in this layer.
Ionosphere
The lower Thermosphere is called the Ionosphere.
The ionosphere consists of electrically charged particles known as ions.
This layer is defined as the layer of the atmosphere of Earth that is ionized by cosmic and solar radiation.
It is positioned between 80 and 400 km above the Mesopause
.Exosphere
It is the outermost layer of the atmosphere.
The zone where molecules and atoms escape into space is mentioned as the exosphere.
It extends from the top of the thermosphere up to 10,000 km.
