Wind speeds generally increase with height between the surface and the tropopause mostly because of:
A)increasing friction.
B)decreasing friction.
C)the pressure gradient force is stronger at high altitudes.
D)the pressure gradient force is stronger at low altitudes.

Question

Quizplus · Accepted Answer

Wind speeds generally increase with height because there is less frictional resistance at higher altitudes. The decreasing friction allows a stronger pressure gradient force to accelerate the air molecules to higher speeds.
