Question

How does latitudal and longitudinal location of india influence the duration of the day and night

Answer 1

Due to the rotation of earth the time differed in different places. To standardize the time of different places of the earth and prevent confusion during long travels, the earth was divided into time zones. This was done by creating time zones by expanding to 15 degrees of longitude. The Greenwich Meridian was chosen as the Standard Meridian of time. The longitude of any place west of GMT(Greenwich Meridian Time) has to be divided by 15 and the time would be that many hours ahead of GMT, and the ones in the east of are that many hours behind GMT.
