Air pressure decreases due to less air mass above.
Explanation: Atmospheric pressure is the weight of the air column above you. As you go higher there is less air overhead, so pressure falls (roughly exponentially with altitude). Weather causes local variations, but the overall trend with altitude is a decrease.
