Definition: The Coriolis effect results from earth's rotation causing freely moving objects to veer toward the right in the Northern Hemisphere and to the left in the Southern Hemisphere. It effects things like wind, ocean currents, airplanes, missiles, but does not effect toilets or sinks.
Examples:
When I fire this missle at you, the missle will veer to the right because the earth under it moves while the missle is in the air.
