At which location does the Coriolis force have the least effect on wind direction?

The Coriolis force, which is a fictitious force observed in rotating systems, is influenced by the rotation of the Earth. It affects the motion of objects, including wind, causing them to curve rather than move in a straight line. The strength of the Coriolis force is dependent on the latitude: it is maximum at the poles and decreases as you move toward the equator, ultimately becoming negligible at the equator itself.

At the equator, the Coriolis effect is minimal because the rotation of the Earth is such that the speed of the surface (due to the Earth's circumference) effectively cancels out the Coriolis effect on wind motion. Consequently, at the equator, wind tends to flow more directly without significant deflection.

In contrast, at the poles, winds are significantly influenced by the Coriolis force, causing them to curve extensively. Therefore, the correct answer identifies the equator as the location where the Coriolis force has the least effect on wind direction, allowing for more straightforward wind patterns without the complicated deflections seen at higher latitudes.
