"Lines of longitude" are conceptual, not physical; there can be as many as we want. For example, there are 3600 "seconds of longitude" between each degree of longitude. That's 60 minutes of arc per degree, and 60 seconds of arc per minute.
Each 'meridian' is a line of constant longitude.
There are an infinite number of lines of longitude on Earth's surface. Each line of longitude represents a meridian and measures distance east or west from the Prime Meridian, which runs through Greenwich, England.
The Prime Meridian is a line of longitude (0°). It goes through every north or south measurementbetween the north pole and the south pole, and no other lines of longitude cross it.
Lines of longitude measure distance east and west from the Prime Meridian, which runs through Greenwich, England. Each line of longitude represents one 360th of a full circle around the Earth.
Each of those lines is a meridian of longitude. They are 180 degrees apart in longitude,so together they form a complete circle around the Earth. That circle is the boundarybetween the eastern and western hemispheres.
Each meridian of longitude joins the north and south poles.

The Greenwich Meridian, also known as the prime meridian or International Meridian, bisects the primary division of time zones. Each time zone is 15 degrees of longitude in width, with local variations, and observes a clock time one hour earlier than the zone immediately to the east. The time difference between two meridian lines is one hour (the time difference between two longitudinal lines is 4 minutes and consequently the time difference between 15 longitudinal lines; or two meridian lines; would be one hour). Refer to link below.The Greenwich Meridian bisects the primary division of time zones. Each time zone is 15 degrees of longitude in width, with local variations, and observes a clock time one hour earlier than the zone immediately to the east. The time difference between two meridian lines depends on where you draw the lines. There is no official standard set of lines that everyone is required to use, and a line can be drawn at ANY longitude. Whatever the longitude difference is between the two meridians you decide to consider, the time difference between them (in hours) is nominally 1/15 of that angle.
Each meridian of constant longitude is a semicircle that joins the Earth's north and south poles. They stay put.
Longitude is labeled from zero (at the Prime Meridian) to 180 degreesin each direction, east and west, from it.
Lines connecting points to the same longitude are called meridians. These lines run from the North Pole to the South Pole and are used to measure the Earth's longitudinal coordinates. Each meridian is defined by its angular distance east or west of the Prime Meridian, which is set at 0 degrees longitude.
All 'lines' between these two parallels are called longitude and each has a number which expresses the number of degrees east or west of the Prime Meridian.
Lines of longitude are referred to as meridians and appear as parallel lines on a globe. These lines converge at the poles and are evenly spaced around the globe from the Prime Meridian at 0 degrees to the 180th meridian.
