Chapter 31, Problem 9RAT

To determine

The correct option for the statement “As air flow up the side of a mountain, the air pressure”.

Answer to Problem 9RAT

The correct option for the statement “As air flow up the side of a mountain, the air pressure” is option (b).

Explanation of Solution

The weather forecasting depends on the pressure of air at that location, so the pressure is an essential factor that decides the weather of a particular region. If the barometric pressure is high in an area, this will cause air to move to a region of lower pressure.

The pressure of air is the force exerted by the molecules per unit volume, as the height increasing the volume of the air decreases that ultimately decreases the pressure of the air, thus atmospheric pressure decreases as the altitude increases.

So, during mountain climbing, the blood from the nose comes out as the pressure of the air decreases and the pressure of the blood inside the body is no longer balanced by the atmospheric air.

Conclusion:

Therefore, the correct option for the statement “As air flow up the side of a mountain, the air pressure” is option (b).
