Question

With reference to "Coriolis force", which of the following statements is/are correct?

  1. 1.

    It increases with increase in wind velocity.

  2. 2.

    It is maximum at the poles and is absent at the equator.

Options

a

1 only

b

2 only

c

Both 1 and 2

Answer
d

Neither 1 nor 2

Explanation

Both statements are correct. The Coriolis force is directly proportional to both the sine of the latitude and the wind velocity (higher speed = greater deflection). It also scales with latitude, meaning it is absent at the equator (sin 0° = 0) and reaches its maximum at the poles (sin 90° = 1).

The Coriolis force depends on latitude, Earth's rotation rate, and wind speed.

Answer: (c).
