The Coriolis Effect

One of the significant changes can be observed after crossing the equator is the manner in which water drains from the sink. North of the equator, water swirls clockwise in the sink basin. South of the equator, water swirls counter-clockwise. The Coriolis Effect causes this, which is the result of the earth’s rotation. Coriolis gives a clockwise acceleration on all free material in the Northern Hemisphere and a counter-clockwise acceleration in the Southern Hemisphere.
