Reasons for the Difference in Day and Night Duration at Kanyakumari and Kashmir
The difference in the duration of a day and night is hardly felt at Kanyakumari but not so in Kashmir due to several geographical and astronomical factors.

Latitude
- Kanyakumari is located near the equator at a low latitude, which means the sun's path is almost perpendicular to the Earth's surface throughout the year.
- This results in almost equal day and night durations throughout the year in Kanyakumari.

Seasonal Changes
- In Kashmir, which is located at a higher latitude, the tilt of the Earth's axis causes significant seasonal changes in day and night durations.
- During summer, the days are long and nights are short, while during winter, the opposite occurs with long nights and short days.

Altitude
- The altitude of a place also affects the duration of day and night. Kanyakumari is at sea level, while Kashmir is at a higher altitude.
- Higher altitudes can have longer periods of daylight due to the way the Earth's atmosphere scatters sunlight.

Twilight Effect
- Places at higher latitudes experience longer twilights, further extending the duration of daylight and night time.

Conclusion
In conclusion, the difference in the duration of a day and night at Kanyakumari and Kashmir is influenced by their latitude, altitude, and the tilt of the Earth's axis. These factors combine to create the distinct day and night patterns observed in these regions.
