The lines on a global grid that run from pole to pole are called meridians of longitude. The prime meridian, which passes through Greenwich, London, is the most well-known and has a longitude of 0 degrees. The meridian at 180 degrees, opposite the prime meridian, is called the International Date Line.

Geographers use the prime meridian as the starting point for measuring longitude around the globe. It helps establish a reference point for determining locations in terms of east-west distance. By using the prime meridian in conjunction with the Equator, geographers can create a grid system to pinpoint any location on Earth.
The prime meridian and the equator are alike because they are both invisible lines that split the earth in half. The equator is horizontal (side to side) and the prime meridian is vertical (up and down). The equator divides the Northern and Southern Hemisphere and the Prime Meridian divides the Western and Eastern Hemisphere.
The prime meridian in located at 0 degress longitude, and passes through Grenich, England.

The geographic grid line 180 degrees of longitude from the Prime Meridian is the International Date Line. This line marks the boundary where the date changes as one travels across it from west to east.

The prime meridian is located at 0 degrees longitude on a coordinate grid. It runs from the North Pole to the South Pole, dividing the Eastern and Western Hemispheres. This line passes through Greenwich, London, and serves as the reference point for measuring longitude around the globe.
There are three norths: true north, magnetic north and grid north. According to www.ordnancesurvey.co.uk, the three norths are defined as follows: Grid North: the direction of a grid line which is parallel to the central meridian on the National Grid. True North: the direction of a meridian of longitude which converges on the North Pole. Magnetic North: the direction indicated by a magnetic compass. Magnetic North moves slowly with a variable rate and currently is west of Grid North in Great Britain.
