Question 1.
Write the size and extent of India.

It accounts for 2.4% of the world’s total area.
(b) India has a land frontier of 15,200 km.
(c) India has a coastline of 7516.6 km including the Andaman and Nicobar islands and
the Lakshadweep islands.
Question 2.
Explain why 82°30′ E an odd value has been chosen as the standard meridian of India.
Answer:
The odd value has been chosen as the standard meridian because the longitudinal
extent of India is 68°7′ E to 97°25′ E and this meridian passes through the centre of
India.
It passes through Mirzapur i.e. the centre of India. Then there is an understanding
among the countries of the world that the degrees of the meridian should be divisible by
712 i,e. 82° 30′ E. This
enables us to overcome the difference of 2 hours of time between Arunachal Pradesh
and Gujarat. The time is Indian Standard Time.
Question 3.
Why is the difference between the durations of day and night hardly felt at
Kanyakumari but not so in Kashmir?
Answer:
The difference in the durations of day and night and Kanyakumari and Kashmir are
respectively due to their latitudinal locations. Kanyakumari is located closer to the
equator and experiences a maximum difference of 45 minutes between day and night.
However, Kashmir lies further away from the equator and experience a significant gap

Question 11. 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 lag of two hours, but the watches
show the same time because the 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. Because the same standard time for the whole country has been adopted, the
watches show the same time in Arunachal Pradesh, Gujarat, and in all parts of the
country.
