Answer: As altitude increases, atmospheric pressure decreases
Explanation:
Atmospheric pressure is defined as the force
per unit area
the air that forms the atmosphere exerts on the Earth's surface:
It should be noted that as the altitude increases less air is above and, therefore the air weights less. This is because the atmosphere losses density as we ascend, causing less air.
However, it is important to point out this decrease in pressure is not linear, since at the beginning (in the first kilometers above sea level) it reduces more rapidly than in the next kilometers above. That is why this relationship between atmospheric pressure and altitude is exponential.
