4. THERMOSPHERE :







                  •This is the fourth and one of the

                  hottest layers of Earth.

                  •

                  •This is where the space shuttles

                  go to study Earth from space.




                  •The air in this layer is very thin

                  and about 99.9% of the

                  atmosphere is said to lie below

                  this particular layer.




                  •Thermosphere also contains the

                  ionosphere. Ionosphere helps in

                  the transmission of radio waves.
