Longiude:
The imaginary lines that run from the North Pole to the South Pole are called
longitudes. They are also called meridians of longitude.
The meridian that passes through Greenwich, in London, is called the Prime
Meridian. It is at 0°.
There are 360 meridians- 180 to the east and 180 to the west of the Prime
Meridian.
The 180° longitude is the International Date Line.
