Show Answer
Correct Answer: D [1, 2 & 3]
Notes:- Kerala is presently under the influence of at least three rainfall triggering weather conditions.
- There are strong Westerly winds flowing-in from the Arabian Sea, and bringing moisture over Kerala.
- Another major cause for an increase in rainfall is the presence of an east-west shear zone located 10 degrees north over the southern peninsula. This vertical zone — that can prevail either in the lower, middle or upper atmospheric levels — allows active winds of high speeds to interact. This zone also allows monsoon winds to remain active, thus causing intense rainfall over the area under its influence.
- The presence of a north-south trough running between Chhattisgarh and Comorin areas, which is located closer to south Kerala is causing widespread rainfall.

Notes:- The power to create new districts or alter or abolish existing districts rests with the State governments.
- This can either be done through an executive order or by passing a law in the State Assembly.
- The Centre has no role in this matter.
- If the state government wants to change the name of a district or a railway station, then the Home Ministry comes into the picture.
