v A globe is a true spherical representation of the Earth.
            v The parallels of latitude are parallel horizontal lines drawn on the Earth north-south, the Equator being the
               longest.
            v The heat zones indicate the temperature zones of the Earth.

            v The meridians of longitude are vertical lines converging at the poles and indicate time.
            v The grid of latitudes and longitudes assist to ascertain the location of a place on a globe or map.
            v One degree of longitude shows a difference of 4 minutes in time.
            v The standard time is set for the whole country according to its relative position to the Prime Meridian.
            v The Indian Standard Time is ahead of Greenwich Mean Time by 5 hours and 30 minutes.
