What is the main reason air pressure decreases with height in the troposphere?
Answer and explanation
Correct answer: The weight of the air column above becomes less
Air pressure is the force exerted by the weight of the air above a particular place. At a higher altitude, a shorter and less massive column of air lies overhead, so its weight and the pressure it produces are lower. Therefore, option A is correct. Ozone increase, meteor burning, and ocean depth do not explain the normal decrease of tropospheric pressure with height.
