The world map above shows lines of longitude and latitude. what is the name of the highlighted line that travels from north to south?

Prime Meridian

Explanation:

The Prime Meridian is the highlighted line often represented in the world map, which travels from the north to the south pole. It is the line that has a longitudinal value of 0°. The measurement is made from this point while traveling in the eastern or western direction. The longitudinal lines are not parallel to each other like the lines of latitude. This prime meridian line is the imaginary longitudinal line that separates the earth into equal parts such as the eastern and western hemispheres.
