If surface winds were influenced only by the pressure gradient force and Coriolis force (i.e. ,without the frictional force),
A)winds would flow in a straight line from areas of higher to lower pressure.
B)winds would flow parallel to isobars and at high rates of speed.
C)there would be no winds at all.
D)the effects would vary depending on surface texture.
E)wind speed and direction would be reduced.

Question

Without the frictional force, winds would flow parallel to isobars and at high rates of speed due to the balance between the pressure gradient force and the Coriolis force. This is known as geostrophic wind.
