Question

LEARN MORE REMARKS The weight of the atmosphere results In P0 at the surface of the oil layer. Then the weight of the oil and the weight of the water combine to create the pressure at the bottom. QUESTION Why does air pressure decrease with increasing altitude? (Select all that apply.) Hot air rises. The weight of the air above is smaller. There s more air below to push up more strongly. Less air above pushes down. Colder air is less dense. The weight of the air below is smaller. Consider what causes pressure in a fluid and how it is related to the fluid above and below the point of interest. Does air contract or expand if cooled, and how does that affect its density?

Explanation / Answer

Atmospheric pressure depends on the density of air around you. As the altitude increases, presence of air decreases due to a lack of living things around you, then the atmspheric pressure will decrease.
