Kanyakumari and Kashmir are two regions in India that experience different changes in the duration of day and night throughout the year. However, the differences in these changes are not felt in Kanyakumari but are felt in Kashmir. This can be explained through the following reasons:


Kanyakumari, located at the southernmost tip of India, experiences very little variation in the duration of day and night throughout the year. This is because it is situated very close to the equator, where the changes in daylight hours are minimal. On the other hand, Kashmir, located in the northernmost part of India, experiences significant changes in the duration of day and night throughout the year due to its proximity to the Arctic Circle.


Kanyakumari experiences only two seasons throughout the year – summer and monsoon. These seasons have little effect on the duration of day and night. In contrast, Kashmir experiences four distinct seasons – spring, summer, autumn, and winter. The changing seasons have a significant impact on the duration of day and night, as the amount of sunlight received by the region changes drastically.


Kanyakumari is surrounded by water on three sides, which helps to regulate the temperature and humidity levels in the region. This, in turn, has an impact on the duration of day and night, as the temperature and humidity levels affect the amount of sunlight that is absorbed by the earth's surface. In contrast, Kashmir is surrounded by mountains, which can block sunlight and cause the region to experience longer periods of darkness.


In conclusion, the differences in the duration of day and night between Kanyakumari and Kashmir can be attributed to their respective locations, seasonal changes, and geographical factors. While Kanyakumari experiences minimal changes in the duration of day and night due to its proximity to the equator and its surrounding water bodies, Kashmir experiences significant changes due to its proximity to the Arctic Circle and its surrounding mountains.
