Lastly, the prime Meridian is a line of longitude that travels from north to south and cuts the world in half between eastern and western hemispheres, like the Equator cuts the globe into the northern and southern hemispheres. The Prime Meridian goes through the Atlantic Ocean and cuts off put of Africa.
