The correct answer is At the North Pole.
The Coriolis Effect is an apparent force that deflects moving objects (like air currents, ocean currents, projectiles) due to the rotation of the Earth. The magnitude of the Coriolis force is proportional to the sine of the latitude. It is zero at the Equator (latitude 0 degrees) and maximum at the poles (latitude 90 degrees North and South), where sin(90) = 1.
The Coriolis effect causes moving air and water to be deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This effect is significant in large-scale atmospheric and oceanic circulation patterns, but negligible for small-scale, short-duration phenomena like the movement of a person or a car.
