The Prime Meridian is 1/2 of a circle.
Its ends are at the north and south poles, and it goes through a suburb of London.
The half of the Earth on one side of it is called the eastern hemisphere, and the half of the Earth on the other side is called the western hemisphere.
"Hemisphere" means half of a sphere.
It's a half circle on the surface of the globe and it is the line that crosses Greenwich in Europe. Hope this helps!
The Prime Meridian is at 0 degrees longitude and divides the Earth into the Eastern and Western Hemispheres. It faces east and west, with the Eastern Hemisphere located to the east and the Western Hemisphere to the west. This imaginary line is crucial for navigation and timekeeping worldwide.
