1. The north-south extent of the country is determined by the 1 2
(a)_________________________ and the longitudinal extent
determines the (b)____________ extent of the country.
2. Why does Itanagar have more difference between local time and 1 2
standard time than Bhubaneswar?
3. Why there is no difference between the local time and the standard 1 2

8. The latitudinal and longitudinal extent of the mainland is about 3+1+1 2
30°. Despite this fact, the east-west extent appears to be smaller =5
than the north-south extent. 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. The
latitudinal extent influences the duration of day and night, as one
moves from south to north.
