Exosphere
Exosphere is the outermost layer of the atmosphere. It extends from the top of the thermosphere to 10,000 km above the earth. In this layer, atoms and molecules escape into space and satellites orbit the earth. At the bottom of the exosphere is the thermopause located around 600 km above the earth.

All Layers of Environment on earth
Exosphere: 600 km to 10,000 km
Thermosphere: 85 km to 600 km
Mesosphere: 50 km to 85 km
Stratosphere: 20 km to 50 km
Troposphere : 6 km to 20 km

These layers are identified based on temperature characteristics i.e. temperature changes, chemical composition, air movement, and density.
