The sun rises two hours earlier in Arunachal Pradesh as compared to Gujarat in the west but the watches show the same time. How does this happen?
India lies between 68°7'E and 97°25'E, making a 28° difference from extreme west (Gujarat) to extreme east (Arunachal Pradesh) of the country. The Earth rotates 360° in 24 hours, i.e., it moves 1° in 4 minutes. Thus, for moving 28° the earth takes 28 x 4 i.e., about 2 hours. As a result, the Sun rises 2 hours earlier in Arunachal Pradesh compared to Gujarat. However, both regions use the same time because they follow the standard time of India, which is set along the Standard meridian of India (82°30'E).
The central location of India at the head of the Indian Ocean is considered of great significance. Why?
The Indian landmass has a central location between the east and the west Asia. The trans Indian ocean routes, which connect the countries of Europe in the west and the countries of east Asia, provide a strategic and significant central location to India. The Deccan Peninsula protrudes into the Indian ocean, thus helping India to establish close contact with west Asia, Africa and Europe from the western coast and with southeast and east Asia from eastern coast. Therefore, the central location of India at the head of the Indian Ocean is considered of great significance.

Why 82°30'E has been selected as the Standard Meridian of India?
82°30'E has been selected as the Standard Meridian of India because it lies in the middle of the eastern and western longitudinal extremities of the country.
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.
