Thermosphere - Navo

•  Based on the vertical temperature profile in the atmosphere, the thermosphere is the highest layer, located above the mesosphere .
•  While in the troposphere and the mesosphere, the temperature decreases with altitude. In the stratosphere and thermosphere the temperature increases with height (called temperature inversion).
•  It is separated from the mesosphere by the mesopause, in which the temperature does not change much vertically. Above the thermosphere, the upper limit of the atmosphere, the exosphere can be found blending intospace . 
• The upper part of the mesosphere and a big part of the thermosphere overlap with theionosphere , which is a region defined on the basis of electric properties.
• The thermosphere and the exosphere together form the upper atmosphere.
