Solution

The exosphere is the outermost layer of the earth’s atmosphere.
Exosphere - The layer above the thermosphere at a distance above 500km of the earth’s surface.
Exosphere act as a transitional medium to a zone under the influence of gravity.
It also helps the atoms to escape from the atmosphere to outer space.
Unlike other atmospheric layers, It is the only layer of the atmosphere that has a distinct shape.
Troposphere - The layer just above the earth’s surface whose distance is between 0 to 10km.
The troposphere contains most of the air and oxygen essential to all living organisms.
Air is used for respiration and other functions for the survival of human beings and forms the earth’s weather conditions
The outermost layer of the atmosphere is exosphere.
