Difference between meridian and longitude?

The longitude of a point on earth is the angle, east or west, between that point and a certain reference line on the earth. If you take a globe or a map and draw a line through all the points that have exactly the same longitude, the line you get is the meridian of that longitude. The reference line is the meridian of zero longitude, called the "Prime Meridian". On that line are all the points on earth that have zero longitude. The line joins the north and south Poles, and passes through the Royal Observatory at Greenwich, a suburb of London.
