The deflection of moving air and water that results from Earth's rotation is known as the a Southern Hemisphere Effect b Northern Hemisphere Effect c Earth's Rotation Effect d Coriolis Effect

D.

Explanation:

an effect whereby a mass moving in a rotating system experiences a force (the Coriolis force) acting perpendicular to the direction of motion and to the axis of rotation. On the earth, the effect tends to deflect moving objects to the right in the northern hemisphere and to the left in the southern and is important in the formation of cyclonic weather systems.
