Question: 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?
Answer: 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 0 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: The central location of India at the head of the Indian Ocean is considered of great significance. Why?
Answer: 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.
