The correct answer is (b), Rotation of the Earth.
The Coriolis effect is an apparent deflection of objects moving in a straight line on a rotating object. It is caused by the Earth’s rotation, which causes the Earth’s surface to move faster at the equator than at the poles. This difference in speed causes objects moving in a straight line to appear to be deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.
The Coriolis effect is most noticeable for objects moving over long distances, such as airplanes and hurricanes. It can also be seen in the way that rivers curve and the way that wind blows.
The Coriolis effect is not a force, but rather an illusion caused by the Earth’s rotation. It is not a real force, but it can have real effects on the way that objects move.
(a) Atmospheric pressure is the force exerted by the weight of the air above a given point. It is not a force that causes wind to deflect.
(c) Temperature is a measure of the average kinetic energy of the molecules in a substance. It is not a force that causes wind to deflect.
(d) Earthâs magnetic field is a field of force that surrounds the Earth. It is not a force that causes wind to deflect.
