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

ANALYSE \& ASSESS - 1 But the Clocks two hours earlier in Arunachal Pradesh as compared to Gujarat in the west. i) India lies bew the same time. How does this happen? ( AS 1 ​ ) • India lies between 6 8 ∘ 7' and 9702 5 ′ East Longitudes. The longitudinal extent of India is • The earth takes 4 minutes to the sun's position to move 1 ∘ of Longitude (360 Longitudes, 24 hours = 4 minutes). India has 30 longitudes approximately 30 × 4 = 120 min or 2 hours. • So sun rises 2 hrs earlier in Arunachal Pradesh compared to Gujarat (if we travel from east to west). So, in order to avoid any confusion of time from place to place we have chosen 8230 as the Standard Meridian. • The Standard Meridian of India passing near Allahabad (Mirzapur) serves as the Standard Time for the whole country. Hence the watches show the same time. • ANALYSE \& ASSESS - 1 But the Clocks two hours earlier in Arunachal Pradesh as compared to Gujarat in the west. i) India lies bew the same time.

☛ Notes and Study Material – Chapter 1 India – Size and Location Intext Questions Page 2 Question 1. Why 82°30′. E has been selected as the Standard Meridian of India? Answer 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? Answer 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. Page 4 Question 1. Find out the number of Union Territories along the Western and Eastern coasts. Answer Union Territories along the (a) Western Coast Lakshadweep, Diu and Daman, Dadra and Nagar Haveli and Mahe (belonging to Puducherry). (b) Eastern Coa...

The local times of places which lie on different meridians are bound to differ. The sun rises two hours earlier in Arunachal Pradesh as compared to Gujaratin the west. This causes a time lag of two hours from Gujarat to Arunachal Pradesh. To avoid confusion due to time differences and to have a standard time for reference, the time along the meridian(82°30' E) passing through Mirzapur (Uttar Pradesh) has been taken as the standard time for the entire country. This is why the watches show the same time.

From the longitudinal extent of India it is observed that the longitudinal expanse is about 30 ofrom west to east. This means that there would be a time-lag of two hours approximately from Gujarat to Arunachal Pradesh. To avoid such differences in local time, Indian standard time has been fixed to give the whole country a uniform time. The local time of the Standard Meridian of 82 o30’E is observed as the Standard Time by the whole country. Because of this reason we find that the sun rises two hours earlier in Arunachal Pradesh as compared to Gujarat in the west but the watches show the same time.
