That depends on the scale of the map you use. On a small scale map (Remember, small scale = big area) longitude lines may be 10 or 15 degrees apart, while on a large scale map, they are probably one degree apart or even 15 minutes (one quarter degree) apart. We can measure them as finely as you want to.
The northern and southern hemispheres each have 360 degrees of longitude. The eastern and western hemispheres each have 180 degrees of longitude. You can use as many or as few 'lines' as you want, to mark off any number of degrees.
The highest longitude lines are the prime meridian at 0 degrees longitude and the 180 degrees longitude line. These lines mark the starting point for longitude measurements to the east and west, respectively.
There are 180 degrees of east longitude and 180 degrees of west longitude, for a grand total of 360 degrees of longitude around the Earth. You're free to draw as few or as many 'lines' through that range on your map or globe as you feel will make you comfortable. There is no standard set of 'lines' that everone is required to use.
The answer is equator
The approximate latitude and longitude lines for, Alexandria Egypt are 31 degrees E. and 31 degrees W.
A complete globe, including Earth, always has 360 degrees. There can be an infinite number of longitudinal lines because longitudinal lines are imaginary constructs and not physical features of Earth itself, so the number of degrees between those longitudinal lines is dependent on the number of longitudinal lines, assuming the longitudinal lines are equidistant. To calculate the number of degrees between these equidistant longitudinal lines, divide 360 degrees by the number of longitudinal lines. A model globe of Earth is typically given 36 lines of longitude. Using the calculation given above, the angle between adjacent longitudinal lines is 360 degrees divided by 36 lines of longitude, or 10 degrees. If 24 lines of longitude are used to represent the 24 time zones, the angle between adjacent longitudinal lines is 360 degrees divided by 24 lines of longitude, or 15 degrees.
one degree, about 111 kilometers at the equator.
The Equator is 0 degrees latitude, and the Prime (or Grenwich) Meridian is 0 degrees longitude.
No. 90 degrees longitude is not a major line of longitude. Only 0 and 180 degrees longitude, which are the Greenwich Meridian and the International Date Line respectively, are major lines of longitude.
New York City is on the longitude 74o west
They are called the lines of longitude. Lines of longitude range from 0 degrees on the prime meridian to 180 degrees.
35 degrees north latitude and 53 longitude
