The Coriolis effect is the result of "the rotation of Earth on its axis".
<u>Answer:</u> Option B
<u>Explanation:</u>
The Coriolis force occurs either inertial or imaginary. That works on objects in movement within a reference frame that rotates in support of an inertial frame. The influence of the effect of Coriolis depends on velocity of Earth and object or substance which is being deflected by the Coriolis effect. For long distances or high velocities, Coriolis effect influence is priority.
This effect explains the wind variations in North Hemisphere to the right initiated by the earth's rotation on its axis. The Coriolis Effect accounts to the wind's circular motion around pressure systems that shift weather patterns in south-eastern USA.
