Contrast in motion of objects moving over the surface of rotating and non-rotating planets. A northward moving object maintains a true course when viewed from two islands on the surface of a non-rotating earth. An object with an eastward component of velocity at the equator overshoots a target at 40N on a rotating earth. The path of the object is deflected to the right relative to objects on the earth's surface.

Objects on the earth's equator travel further (and faster) than objects at higher latitudes. A site located along the equator travels at 1675 km/hr, whereas a site along latitude 40N (or 40S) has a velocity of 1284 km/hr. It is this contrast in velocity that results in the Coriolis Effect.
