Correct answer: the pressure that air exerts as it is being pulled to Earth by gravity.

More detail: air pressure (atmospheric pressure) is the force per unit area produced by the weight of the column of air above a point. It's measured in pascals (Pa), millibars (hPa), or inches of mercury (inHg). It is not wind speed, temperature, or moisture (humidity).
