Question.1. Why 82°30′E has been selected as the Standard Meridian of India?
Ans. From Gujarat to Arunachal Pradesh there is a time lag of two hours. Hence, time along the Standard Meridian of India (82° 30′ E) passing through Mirzapur (in Uttar Pradesh) is taken as the standard time for the whole country. Otherwise different regions of India would have different times which would create problems; so, to have one common standard times for the whole country has been selected and called Indian Standard Time (IST).
Question 2. Why is the difference between the duration of day and night hardly felt at Kanyakumari but not so in Kashmir?
Ans. The day and night are nearly of the same duration at the equator. As Kanyakumari is quite near the equator at 8°4’N the day-night difference is hardly one hour there, and therefore, the duration of day and night is hardly felt at Kanyakumari.
On the other hand, as we move away from the equator to the poles the variations in duration of day and night become greater. Kashmir is over 30° away from the equator and so the difference in duration of day and night is more there and we feel that difference.

Question 3. 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?
Ans. From Gujarat to Arunachal Pradesh there is a time lag of two hours, but the watches show the same time because the time along the Standard Meridian of India (82° 30′ E) passing through Mirzapur in Uttar Pradesh is taken as the standard time for the whole country. Because the same standard time for the whole country has been adopted, the watches show the same time in Arunachal Pradesh and Gujarat and in all parts of the country.
Question 4. The central location of India at the head of the Indian Ocean is considered of great significance. Why?
Ans. The Indian landmass has a central location between East and West Asia, India is a southward extension of the Asian continent. The trans Indian Ocean routes which connect the countries of Europe in the West to the countries of East Asia provide a strategic 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 South-East and East Asia from the Eastern coast. No other country has a long coastline on the Indian Ocean as India has. Thus, India’s eminent position in the Indian Ocean justifies the naming of an ocean after it.
