________ is the pressure exerted by air on an object.
Atmospheric pressure is the pressure exerted by air on an object.
Atmospheric pressure is the pressure exerted by the weight of air present in the atmosphere.
It is commonly measured with a barometer, in which a column of mercury in a glass tube rises or falls as the weight of the atmosphere changes.
