Question

Quizplus · Accepted Answer

Geostrophic flow occurs when the pressure gradient force and the Coriolis force are in balance, which is true for A. It occurs in both the atmosphere and the oceans, not just the upper atmosphere, so B is false. Friction is negligible or absent in geostrophic flow, so C is true as well. Therefore, the correct answer is D.
