ICSE Class 9 Total Geography Ch 2:Geographic Grid- Latitudes and Longitudes

Answer 1

The lines of longitude or meridians are imaginary lines that pass from the north to the south of the earth, converging at both Poles and are farthest from each other at the Equator.

Prime Meridian passing through Greenwich Observatory of London is considered as the 0 degree longitude.

Each degree of a longitude is divided into minutes and seconds for accurate calculations of the locations.

Each degree is found to be 111 Km maximum at the Equator region.

Two longitudes have time difference of 4 minutes and thus, the time of a location is calculated as 4 x longitude degree from Prime Meridian.
