Actually, Atmosphere plays a very good important to us all Humans, the reason why the Atmosphere is thinner in both North Pole and South Pole because the climate affects the Gases in the Atmosphere, mainly the reason because the temperature there is below freezing point the tendency is the Gases stay at stationary movement and suspending their movements remember that when the temperature reaches the 0 degrees celcius all the movements of molecules becomes stationary and suspends making each atom of each gas is inactive to produce movement and their reactions also., so iend this but you can check from other resources thanks and i hope this has a lot information to you
