The Coriolis force is maximum at __?

Poles
The Coriolis effect influences the paths of moving objects on Earth and is caused by Earth s rotation. Because Earth s surface rotates at different velocities at different latitudes, objects in motion tend to veer to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. The Coriolis effect is nonexistent at the equator but increases with latitude, reaching a maximum at the poles.
