Question

Describe the implication of India's longitudinal extent

Answer 1

* The longitudinal extent of India is 68o7'E to 97o25'E. 

* The implications of longitudinal extent of India are: 

- India lies completely in the eastern hemisphere. 

- There is difference of two hours between the times of the eastern-most and western-most parts of India. 

- 82 1/2oE is selected as the Standard Meridian of India. 

* The longitudinal extent of India is 8o4'N to 37o6'N. 

Answer 2

Its implications are-

i. The tropic of cancer (23 Degree 30 Minutes North) divides

India into nearly two equal parts. The southern half lies in

the hot tropical zone whereas the northern half lies in the

warm temperate/ sub tropical zone.

ii. Temperature generally decreases with increasing latitude.

The tropical part (peninsular India) of India being near to the

equator has warm and tropical climatic conditions with no

distinct winter. The sub tropical part (northern India) has a

more or less extreme climate i.e. hot summers and cold

winters. This variation in climate from warm Kerala to cold

Kashmir is mainly due to large latitudinal extent.

iii. The difference in the duration of day and night also

increases from South to North. It is less than one hour

difference (about 45 minutes) at Kanyakumari but reaches

nearly 5 hours in the extreme north of Kashmir.

The longitudinal extent of India is 68 Degree 7 minutes East to 97 Degree 25
