Briefly describe the layers of the atmosphere:Troposphere-Exosphere-St ratosphere-Mesosphere-Thermosphere-

Explanation:

-Troposphere. It is the lowest layer and encompasses the Earth's surface up to an average height of 12 kilometers; about 17 kilometers in the equatorial regions and about 9 kilometers at poles

- Stratosphere.Separated from the troposphere by the tropopause is this layer containing 19 percent of the atmospheric gases, but very little amount of water vapour.

-Mesosphere. It is located above the stratosphere up to a height of 80-85 kilometers in the mid-latitudes, where the mesopause is located.

-Thermosphere. From the upper limit of the mesopause extends the thermosphere, known as the upper atmosphere.

-Exosfera. It is the last layer, the outerest until connected with the solar wind.
