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. A

   1 only

   1 only. The pole/equator pattern (2) is also keyed.

2. B

   2 only

   2 only. Magnitude also rises with wind speed (1).

3. C

   Both 1 and 2

   Both. Coriolis increases with velocity; max at poles, zero at equator.

4. D

   Neither 1 nor 2

   Neither. Both textbook properties hold.

Summary. Official key is (c) both. Coriolis acceleration is 2Ωv sinφ. It therefore increases with wind speed and with latitude: maximum at the poles, zero at the equator. Both statements are correct.
