[ANSWERS]
- 97025’ E
- 6807’ E
- 3706’ N
- 804’ N
- The Southernmost point of India is Indira Point.
- The Indira point is situated in the Great Nicobar group of Island in Andaman Nicobar island groups.
- which is located in the eastern Indian Ocean at 6°45'10″N and 93°49'36″E. This is not on the Indian mainland but within the Union Territory of Andaman and Nicobar Islands.
- It is not visible today because it was submerged under the sea in the 2004 Tsunami.
- The tropic of cancer is the most important latitude of the country.
- It is situated at 23 ½ N.
- The tropic of cancer divides the country into two equal parts. in which the upper half is having a tropical climate while the lower half is having a sub tropical climate.
- 82030’ E, longitude is the most important longitude of our country.
- To avoid confusion and chaos in all activities to be caused by having a different local time for different places.
- The central Meridian 82030’ E is taken as the Indian Standard Time.
- It is accepted all over the country for uniformity of time.
- 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.
- Every country has a Standard Time to avoid confusion of time.
- It is the time of its Central or Standard Meridian.
- Each Meridian has its own local time which is the sun time or local time of that particular place.
- To avoid confusion and chaos in all activities to be caused by having a different local time for different places the central meridian is selected as Standard Time.
- Some Countries whose size is very large they have their different time zones.
- India has a longitudinal extent of 300. Due to this, there is a time lag of two hours between the sunrise on the easternmost and the westernmost horizons of India.
- Due to the rotation, the earth takes 4 minutes to rotate through 10 of longitude. The difference in time is one hour for 150 of longitude.
- Therefore, for a longitudinal extent of 300 of India, there is a time lag of two hours. When it is 6 a.m. in Arunachal Pradesh, it is still 4 a.m. in Gujarat and Jaisalmer.
- But the watches in all parts of India are run according to standard time measured from 82 ½0 longitude.
- So the watches in Arunachal Pradesh and Jaisalmer show the same time despite the different sunrise.
- The central location of India at the head of the Indian Ocean is considered of great significance because:
- It has given India a strategic advantage due to the Trance Indian ocean routes which connect the countries of Europe in the west and the countries of East Asia.
- This 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.
- The vast coastline and the natural harbors have benefited India in carrying out trade and commerce with its neighbouring and distant countries.
- It has given India a distinct climate than the rest of the Asian Continent.
- In fact, India only has the longest coastline in the Indian Ocean in the world.
