Question

why is the difference between the duration of day and night hardly felt at Kanyakumari but not so in Kashmir

Answer 1

This is because Kanyakumari is nearest to the equator and as we know that near to equator there are no changes of duration felt because the sun ray directly falls on it and in contrast to it Kashmir receives slanting rays hence they feel the durations more ...

Answer 2

As Kanyakumari is quite near the equator at 8°4'N the day-night difference is hardly one hour there, and therefore,

theduration of day and night ishardly felt at Kanyakumari. ...Kashmir is over 30° away from the equator and so thedifference in duration of day and night is more there and we feel that difference.
