What generally happens to air pressure with increasing height in the atmosphere?
Answer and explanation
Correct answer: It decreases
Air pressure is caused by the weight of the air above a particular point. When altitude increases, the vertical column of air above becomes shorter and contains fewer molecules, so its weight and pressure decrease. Thus option B is correct. Pressure does not remain constant, and it does not first become zero and then rise; it generally falls continuously, although the rate of decrease can vary.
