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:

  1. 1 only
  2. 2 only
  3. Both 1 and 2
  4. Neither 1 nor 2

Answer

Both 1 and 2

1. It increases with increase in wind velocity — Correct. Coriolis force acting on a moving body is proportional to its velocity; faster winds experience greater deflection.

2. It is maximum at the poles and is absent at the equator — Correct. Coriolis effect varies with latitude: it is zero at 0° and maximum at 90°.

Therefore, both 1 and 2 are correct.
