"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.

Are latitude lines called meridian?
Each 'meridian' is a line of constant longitude.
How are the equator and prime meridian related to latitude and longitude?
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.
What is the time difference between two meridian lines?
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.
In which direction do longitude lines run?
Each meridian of constant longitude is a semicircle that joins the Earth's north and south poles. They stay put.
What is the highest degree for the lines of longitude?
Longitude is labeled from zero (at the Prime Meridian) to 180 degreesin each direction, east and west, from it.
What do lines of longitude or meridians extend from?
Each meridian of longitude joins the north and south poles.

What are the lines that run from 20 north latitude to 20 south latitude?
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.
What does the parallel and meridians have in common?
Meridians are lines of longitude. The meridian lines go from the North pole to the South pole, such that all the lines converge at a single point on each pole. These lines measure degrees east and west of the prime meridian, which is located at 0 degrees.
A line of longitude is a measurement of what direction?
All lines of longitude have the same length. Each one is 1/2 of the earth's polar circumference ... roughly 12,437.6 miles. (rounded)
What direction are meridians?
Every meridian is an imaginary semi-circle between the north and south poles. There are an infinite number of them, each one is more than 12,000 miles long, and every point on the same meridian has the same longitude.
What angle do lines of longitude cross with lines of latitude?
Meridians of constant longitude cross parallels of constant latitude. Parallels of constant latitude cross meridians of constant longitude. At each intersection of a meridian and a parallel, the lines are perpendicular (form 90° angles).
What is the difference between a prime meridian and a meridian?
The time meridian is each standard time zone roughly centered on a line of longitude exactly divisible by 15 degrees and the prime meridian is the starting point for the standard time zones an arbitrary longitude line.
