B)horizontal pressure gradients are the same as vertical pressure gradients
C)horizontal pressure gradients are larger than vertical pressure gradients
D)pressure is relative constant

Question

Quizplus · Accepted Answer

In the upper atmosphere, the air density decreases with altitude, which means that the vertical pressure gradient is larger than the horizontal pressure gradient. Therefore, option A is the correct answer.
