North to South
North - south
The 'longitude' of a place is its angle east or west of the Prime Meridian .
Latitude lines run east-west, parallel to the equator, while meridian lines run north-south, converging at the poles.
To sail along a meridian, one must sail true north or true south. Meridians of longitude run N/S.
Every meridian of constant longitude joins 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.
Each meridian of constant longitude is a semicircle that joins the Earth's north and south poles. They stay put.
The equator runs West-East and the prime meridian (Greenwich meridian) runs North-South.

The longitude of every point on Earth, from the Prime Meridian out to halfway around the world in the westerly direction is labeled "west longitude". The longitude of every point on Earth from the Prime Meridian out to halfway around the world in the easterly direction is labeled "east longitude".
Meridians run from the North Pole to the South Pole and are lines of longitude on the Earth's surface. They help define points on the globe by indicating how far east or west they are from the Prime Meridian.
Every meridian of constant longitude joins the north pole to the south pole.
