Answer:
b. the earth’s rotation
Explanation:
Since the Earth rotates, we experiment an apparent force known as the Coriolis force or the Coriolis effect. }This deflects the direction of the wind to the right in the northern hemisphere and to the left in the southern hemisphere causing the wind-flow around low and high-pressure systems circulates in opposing directions in each hemisphere. This is why winds blow anticlockwise around low pressure and clockwise around high pressure in the northern hemisphere and visa versa in the southern hemisphere.
