North Pole
total number of merdians
They meet at the North and South Poles.
Meridians run from north to south on the surface of the Earth, connecting the North Pole to the South Pole. They are the lines of longitude used in geospatial coordinate systems to indicate angular distance east or west from a prime meridian, such as the Greenwich Meridian.
The two imaginary lines that divide the earth in half are the Equator (divides the earth into Northern and Southern Hemispheres) and the Prime Meridian (divides the earth into Eastern and Western Hemispheres).
