4. Its longitudinal extension is 68 degree 7’ E to 97 degree 25’ E
5. Tropic of Cancer passes through the middle of India.
6. The north to south distance of mainland India is 3214 km.

4. India has a land boundary of about 15,200 km.
5. The total length of the coastline of the mainland, including Andaman and Nicobar and Lakshadweep,is 7,516.6 km.

Que 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?

1. Earth rotates from west to east, so Arunachal Pradesh in the east of India experiences sunrise earlier than Gujarat in the west.
2. The longitudinal extent of India is from 68°7' E to 97°25' E.
3. There is a 30-degree longitudinal difference between the west and east of India.
4. Earth takes 4 minutes to cover 1 degree of longitude.
5. Therefore, there is a 2-hour difference between East Arunachal Pradesh and West Gujarat in India.
6. To address this issue, the Indian government selected a central longitude of 82°30' E, which passes through the city of Allahabad in Uttar Pradesh.
7. People all over India follow the time based on this meridian, known as Indian Standard Time (IST).
8. This is the reason the sun rises two hours earlier in Arunachal Pradesh in the east than in Gujarat in the west, but the clock shows the same time.

Que 4: The central location of India at the head of the Indian Ocean is considered of great significance. Why?

1. The central location of India at the head of the Indian Ocean is considered of great significance because
2. The Deccan Peninsula protrudes into the Indian Ocean helps India to establish close contact with West Asia, Africa and Europe from the Western coast and with the Southeast and East Asia from the Eastern coast.
3. The long coastline and the natural harbours handle a significant percentage of the country’s foreign trade
4. It has given India a distinct climate than the rest of the Asian Continent.
