The true statement about the air pressure acting on the roof of your house is:
**It comes from the column of air above your roof.**
Air pressure is exerted by the weight of the air above a given point. This means that the air pressure on your roof is determined by the total weight of the air extending from your roof to the upper atmosphere. The pressure acts uniformly in all directions, but the significant factor in this case is the weight of the air column directly above the roof. The air pressure does not primarily come from air within a few feet of the rooftop; rather, it is influenced by the entire column of air.
