Reasons for the difference between the durations of day and night in Kanyakumari and Kashmir:

Geographical Location:
- Kanyakumari is located near the southern tip of the Indian peninsula, close to the equator, resulting in almost equal day and night durations throughout the year.
- Kashmir, on the other hand, is situated in the northern part of India, closer to the Arctic Circle, leading to significant variations in day and night lengths.

Earth's Tilt:
- The tilt of the Earth's axis plays a crucial role in the lengths of day and night.
- In Kanyakumari, the tilt causes the sun to be nearly overhead throughout the year, resulting in shorter differences between day and night.
- In Kashmir, the tilt causes the sun's angle to vary significantly, leading to longer days in summer and longer nights in winter.

Seasonal Changes:
- Kanyakumari experiences minimal seasonal changes due to its proximity to the equator.
- Kashmir, being farther from the equator, faces distinct seasons with varying day and night lengths.

Atmospheric Conditions:
- The atmospheric conditions in Kanyakumari, being close to the sea, also contribute to the moderation of day and night durations.
- In Kashmir, the mountainous terrain and continental climate lead to more pronounced differences in day and night lengths.
