how does air pressure change as altitude (distance from earths surface) increases?
○ air pressure does not change
○ the relationship between air pressure and altitude is erratic and unpredictable
○ air pressure decreases
● air pressure increases

Explanation:

Air pressure is caused by the weight of air molecules above a given point. As altitude increases, there are fewer air molecules stacked above, so the weight (and thus pressure) exerted by the atmosphere decreases in a predictable way.

Answer:

air pressure decreases
