Question 1.
Why 82°30’E has been selected as the standard meridian of India?
Answer:
82° 30’ E has been selected as the standard meridian of India to avoid confusion associated with time and to creat harmony in time through the country. The longitudinal extent of India is 30°. According to international convention the longitude that a country selects, should be divided by 7.5° and the nearest multiple of 7.5° is 82.5°. So, 82.5 E or 82° 30’ east has been selected as 1ST.
Question. 2.
Why is the difference between the durations of day and night hardly felt in Kanniyakumari but not so in Kashmir?
Answer:
Day and night are almost of 12 hours each at the equator. Since, Kanniyakumari is located quite near the equator, the difference between the duration of day and night is hardly felt at Kanyakumari. As we move away from the equator to the poles, difference between the duration of day and night becomes more. Since, Kashmir is far away from the equator, the’difference in duration of day and night is more there.

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?
Answer:
From Gujarat to Arunachal Pradesh, there is a time difference of two hours. This happens because the latitudinal and longitudinal extent of India is about 30°. Arunachal Pradesh is in the east. Here sun rises earlier as compared to Gujarat. But the watches show the same time. Because the time along the Standard Meridian of India passing through Mirzapur is taken as the standard time for the whole country. This is the reason the watches in India show the same time.
Question 4.
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 the East and West Asia. India is a southward extension of the Asian continent.
- The trans India Ocean routes, which connect the countries of Europe in the West and the countries of East Asia, provide a strategic central location of India.
- Deccan peninsula protrudes into the Indian Ocean which helps India to establish close contact with West Asia, Africa and Europe from the western coast and with southeast and East Asia from the eastern coast.
- No other country has a long coastline on the Indian Ocean as India has and indeed, it is India’s eminent position in the Indian Ocean, which justifies the naming of an ocean after it.
