Answer: The correct options are:
<em>exerts more pressure as it increases
</em>
<em>measures how tightly molecules are packed
</em>
<em>equals mass divided by volume</em>
Explanation:
Air density can be described as mass per unit of volume of the volume of air.
As the altitude increases, the air density tens to decrease. Hence, option A is not correct.
The density of the air determined how many atoms of air can occur in a particular volume, In other words, it determines how tightly or loosely atoms of air are packed in a particular volume.
Hence, when the air density will increase, the molecules will be more tightly packed and the pressure will be more.
It's gets colder, wetter, and not much sun is received.
Mountain effect refers to the windward side of the mountain receiving precipitation. It is also the effect of rough terrain on radio-wave propagation. Thus, it caused reflections that produce errors in radio direction-finder indications.
