latitude
The lines on a global grid that run from pole to pole are called meridians of longitude. The prime meridian, which passes through Greenwich, London, is the most well-known and has a longitude of 0 degrees. The meridian at 180 degrees, opposite the prime meridian, is called the International Date Line.
Lines of latitude run round the earth parallel to the Equator. Lines of longitude run from pole to pole, crossing the Equator at 90 degrees.
lines of equal longitude, a.k.a. meridians
No. Longitudinal lines run parallel to the Prime Meridian. Latitudinal lines run parallel to the Equator.
Grid line.
No. Lines of longitude or meridians are not parallel.
Longitude lines run from pole to pole.

longitude
In a grid system, the lines that run "up and down" are used to measure distances "left and right". The lines of longitude run north and south from the North Pole to the South Pole, and define 360 degrees of measurement : 180° east and 180° west (the same end point).
Lines of latitude run round the earth parallel to the Equator. Lines of longitude run from pole to pole, crossing the Equator at 90 degrees.
longitudinal lines run north/south; Latitudinal lines run east/west
