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.
Longitude is the differnce of east and west. Lattidtude is the difference of north and south.
.......i know its a little confusing i dont get it but thats just how i learned it ..... hope i helped! :D
Each 'line' of longitude represents a different angle
measured from the Prime Meridian.
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 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.
Longitude
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.
A meridian of longitude is an imaginary line made up of all the points on earth that have the same longitude, whatever that number is. If you draw any meridian of longitude on a globe, it looks like a solid half-circle between the north and south poles.

Nominally 180° of longitude, or halfway around the Earth.

90 degrees west longitude
A meridian of longitude is an imaginary line made up of all the points on earth that have the same longitude, whatever that number is. If you draw any meridian of longitude on a globe, it looks like a solid half-circle between the north and south poles.
35 degrees
A meridian of longitude is an imaginary line made up of all the points on earth with that longitude. If you were to draw any meridian on a globe, it would look like a solid half-circle between the north and south poles.
90 degrees
Every meridian ('line') of longitude is a semicircle on the earth's surface, running between the north and south poles. Every meridian runs through all possible latitudes, and every point on a meridian has the same longitude.
