D)Air density decreases in a completely different way than air pressure decreases.

Question

Quizplus · Accepted Answer

Both air density and air pressure decrease as altitude increases, and they do so in a similar manner because both are influenced by the decrease in the weight of the overlying air. As altitude increases, there is less air above a given point, leading to a decrease in both the pressure exerted by the air (air pressure) and the number of air molecules in a given volume (air density).
