The Prime Meridian is numbered zero degrees. Meridians, or lines of longitude, are numbered with increasing numbers of degrees both east and west of the Prime Meridian. On the opposite side of the world from the Prime Meridian is 90 degrees, which is also the International Date Line.

How are the parallels and meridians numbered?
Parallels are numbered north or south from the equator (starting at 0 degrees) towards the poles, with the equator at 0 degrees. Meridians are numbered east or west from the Prime Meridian (located at 0 degrees) towards the International Date Line, with the Prime Meridian at 0 degrees.
How are the paralles and meridians numbered?
Parallels are numbered based on their angular distance north or south of the Equator, with the Equator itself as 0 degrees. Meridians are numbered based on their angular distance east or west of the Prime Meridian (located in Greenwich, England), with the Prime Meridian itself as 0 degrees.
Where do the meridians meet?
The meridians meet at the poles, which are the points on Earth's surface where the lines of longitude converge. At the North Pole, all lines of longitude meet, and the same is true for the South Pole.
How many meridians are there on the earth surface?
There are a total of 360 meridians on the Earth's surface, running from the North Pole to the South Pole. Each meridian is spaced 1 degree apart, helping to define longitudinal coordinates on maps and globes.
On a globe the meridians converge toward the poles What is the pattern of meridians on the Mercator?
On a Mercator projection, meridians appear as straight, parallel lines running from top to bottom of the map, spaced evenly apart. This is because the Mercator projection is a cylindrical map projection that preserves straight lines of constant bearing, resulting in meridians being stretched vertically towards the poles.
