The direction of the pressure gradient runs __________ to isobars.
A)parallel
B)perpendicular
C)at an angle
D)over

Question

Quizplus · Accepted Answer

The pressure gradient force always flows perpendicular to the isobars. Isobars are lines of constant pressure and gradient means change in pressure over distance, so the direction of the pressure gradient force must be perpendicular to the direction of the isobars to create the necessary pressure difference to drive the wind flow.

The Direction of the Pressure Gradient Runs __________ to Isobars
