Question

why is there difference between duration of day and night felt at kanyakumari but not at kashmir?

Answer 1

I think that it happens due to the longitudinal and latitudinal extend of India

Answer 2

The day and night are nearly of the same duration at the equator. As Kanyakumari is quite near the equator at 8°4'N the day-night difference is hardly one hour there, and therefore, the difference in duration of day and night is hardly felt at Kanyakumari. On the other hand, as we move away from the equator to the poles the variations in duration of day and night become greater. Kashmir is over 30° away from the equator and so the difference in duration of day and night is more there and we feel that difference.
