As the altitude increases the air density decrease because of weaker gravity and these led to more distance between air molecule and the space between gas is increased.
The answer is option D.
What is the effect of the increase in height?
As the height increases, the pressure increases. - As the height increases, the air density increases. - Air pressure and congestion are very low at sea level. - Heavy air is more pressurized than small dense air.
Why does the pressure rise at higher altitudes?
The gravitational pull between the earth and the air atoms is much larger than those distant molecules - they are heavier - pull them closer and increase the force (energy per unit) between them.
