The only one that does not apply is the second one, that air pressure does not affect wind. 1) The air, like any other substance close to Earth, has mass and therefore is attracted by the Earth, i.e. air has weight. Given that the layer of air reaches a height of many kilometers, it exerts the atmosphere (the air) exerts pressure on the bodies. 2) Given the at higher altitude the layer of air over the bodies is less than at lower altitudes, atmosphere pressure decreases as altitude increases. 3) You know that when the air pressure changes you ears experience an unbalaces and the balance can be restored by popping them.
