Question

Quizplus · Accepted Answer

As altitude increases, the air pressure decreases. This is due to the decrease in density of the air molecules at higher altitudes. However, the rate of pressure decrease is not constant but rather decreases with altitude. This is because the higher in altitude an object is, the less pressure there is pushing down on it from the weight of the air above it.
