The rotation of the earth affects the wind direction. The difference in the wind from the north pole from A to B is due to the Coriolis effect. Thus, option A is correct.
Coriolis effect or force is the difference in the ocean currents and weather patterns due to the rotating movement of the earth. In the northern hemisphere, the forces affect the direction of the wind in the counterclockwise direction.
The curves and rotation affect the direction of the wind as the earth is spherical. The winds in the southern hemisphere change in a clockwise direction but at the equator remain zero. It is the absence of curves that makes the direction straight.
Therefore, option A. the Coriolis effect changes the actual movement and direction of the wind around the earth.
