Question

Explain the implications of the latitudinal extent and longitudinal extent of India.

Answer 1

india lies completely in the northern hemisphere

there is a difference between day and night 45 mins in kanyakumari and 5 hrs in jammu kashmir

tropic of cancer passes through indaia and divides the country into almost two equal halves.

Answer 2

Implications of the latitudinal extent of India
(a) The Tropic of Cancer 23° 30' N divides India into ' two parts. The Southern part of India lies in the Tropical zone and northern part lies in Sub-tropical zone.

(b) The southern part of India does not have difference in the duration of day and night while northern part shows difference.

(c) Northern part has high annual range of temperature whereas southern part has low annual range of temperature.

Implications of the longitudinal extent of India
(a) India extends from 68° 7’ E and 97° 25’ E longitudes. There is a difference of 29° 18’ between eastern and western extremes of India.

(b) For every 15° of longitudinal difference, there .is corresponding time difference of 1 hour. As a result of this variation, Arunachal Pradesh is nearly 2 hours ahead of Gujarat in local time.

(c) In order to avoid this difference of 2 hours, 82°30’E longitude has been selected as Prime Meridian for the Indian Standard Time.
