With reference to "Coriolis force", which of the following statements is/are correct ? 1. It increases with increase in wind velocity. 2. It is maximum at the poles and is absent at the equator. Select the answer using the code given below :
A
1 only
B
2 only
C
Both 1 and 2
Correct Answer
D
Neither 1 nor 2
Explanation
Both statements are correct because the Coriolis force is directly proportional to the wind velocity and the sine of the latitude, meaning it increases with speed and reaches its peak at the poles while vanishing at the equator. Option (b) is the most tempting wrong choice if one focuses only on the latitudinal variation, but the force's magnitude is fundamentally dependent on the object's speed as well. The core concept tested is the physical properties and spatial distribution of the deflective force generated by Earth's rotation.
