Why does air pressure decrease with height in the troposphere?
Answer and explanation
Correct answer: Because the weight of air above decreases with height
Air pressure is the force exerted by the weight of the air column above a place. As altitude increases, the column contains less air and therefore weighs less, so pressure decreases. Option A correctly describes this relationship. The other options are unrelated: ocean size, the apparent size of the Sun, and Earth’s rotation do not explain the vertical pressure change.
