Why is the difference between the durations of day and night hardly felt at Kanniyakumari but not so in Kashmir?

The difference between the durations of day and night is hardly felt at Kanniyakumari because it lies close to the equator. At equator the sun rays are straight and the duration of day and night are equal. On other hand, Kashmir lies in north of India, in temperate zone where Sun rays are tilted and therefore, there is considerable difference between duration of day and night.
