Mesosphere
the region of the earth’s atmosphere above the stratosphere and below the thermosphere
Thermosphere
the region of the atmosphere above the mesosphere and below the height at which the atmosphere ceases to have the properties of a continuous medium
Exosphere
the outermost region of a planet’s atmosphere.
Temperature
