(UPSC/MPPSC SPECIAL) it is clear that atmosphere starts from Earth surface but scientists have different views about its maximum height. On the basis of information provided by radars, balloons, rockets, satellites at present large number of scientists agree on a point that the height of atmosphere is 29000 kilometer and layer upto 800 kilometer is considered as important part of atmosphere. On the bases of air pressure, temperature and weather phenomena, out of the total amount of major gases in atmosphere 97% are found upto 29 km of height from Earth while 50% are found upto 5.6 kilometers only. In 20th Century with the help of advanced technical devices, scientists have succeeded in solving major mysteries about atmosphere. Teisserence de Bort, S. Petteisun, Sir Napier shaw, Picardy, Kennelly Heaviside, Ferrel etc. have played an important role in this field. Atmosphere may be divided into layers or spheres on the basis of height, every layer having its own importance. Boundaries of these layers are also arbitrarily established as other natural boundaries.
