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
- India
is a vast country, lying entirely in the Northern hemisphere. The main land
extends between latitudes 8°4’N and 37°6’N and longitudes 68°7’E and 97°25’E of the mainland
is about 30°.
The earth moves around its axis from
west to east and completes one rotation (360°) in about 24 hours, so the earth
moves 1° in 4 minutes. The longitudinal extends
of India is between Arunachal Pradesh (97°25’E)
and Gujarat (68°7’E) is approximately
30°. Because of this gap there is a difference of two hours (30° x 4 Minutes =
120 Minutes means 2 Hours) between these two states. Arunachal Pradesh is
located in the east and hence, sun rises earlier here as compared to Gujarat. 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 and this is why the watches in both the
states show the same time.
4 The central location of India at the head of the
Indian Ocean is considered of great significance. Why?
Answer - Location of
India at the head of the Indian Ocean is considered significant because:
(i) India has got strategic advantage because of the
Trans Indian Ocean routes that connects the Western European countries with the
countries of East Asia.
(ii) The location of India has helped her in establishing close ties with West
Asian and African and European countries from the western coast and with the
Southeast and East Asian countries from the Eastern coast. India’s ties with
other countries are based on several factors for physiological, anatomical,
spiritual, technical, and material knowledge.
