Which of the following statements is true regarding the relationship between air pressure and altitude?
A)as one moves lower in the atmosphere, pressure decreases, as one moves closer to the earth's surface, pressure decreases
B)as one moves up in the atmosphere, pressure increases, as one moves closer to the earth's surface, pressure increases
C)as one moves lower in the atmosphere, pressure decreases, as one moves closer to the earth's surface, pressure increases
D)as one moves up in the atmosphere, pressure decreases, as one moves closer to the earth's surface, pressure increases

Question

Quizplus · Accepted Answer

As one moves up in the atmosphere, there are fewer air molecules above, resulting in a decrease in air pressure. Similarly, as one moves closer to the earth's surface, there are more air molecules above, resulting in an increase in air pressure. Therefore, as altitude increases, air pressure decreases, and as altitude decreases (or as one moves closer to the earth's surface), air pressure increases.
