True or false The Coriolis effect is caused by the jet stream.

The answer is false. The Coriolis effect is not caused by the jet stream. It is caused by the rotation of the Earth. The Coriolis effect is the apparent reversal of rotation of storms and the direction when draining water in the sink or toilet when you cross the equator. In the Southern hemisphere, the rotation is clockwise and in the Northern hemisphere, it's counter-clockwise.
