When we have a pile on with bodies on top of each other, who has the most weight on top of them...the ones on the bottom or the ones on top of the pile? Same with air. There is more air piled on top of the lower altitudes than on top of the higher ones. So there is more pressure on the bottom than on top.

When altitude increases the air has a large space to move so there isn't much pressure put into the air
