Lines of Longitude or Meridians
isochronic lines.
Meridians are not parallel. Apart from that, what is the question?
A map can be distorted by shapes, sizes, lines of latitude and longitude and politics,
A grid reference system, also known as grid reference or grid system, is a geographic coordinate system that defines locations in maps using Cartesian coordinates based on a particular map projection. Grid lines on maps illustrate the underlying coordinate system.
latitude and longitude Co-ordinates
The horizontal lines are called latitudes and the vertical lines are called longitudes.
That's the vertical lines.
Vertical first.
Yes. Longitude lines on a map are vertical and latitude lines are horizontal. But it could be the other way around too. It depends on how you hold your map.
It depends on the scale of the map. On a map of the world or a continent, the parallel lines will generally go horizontally across the map - East to West. For a large scale map, showing a small country or a local area, the vertical lines (North - South) will also be shown as parallel.
By vertical lines, like meridians, but not always straight.
It is called a grid system (or map coordinates), and is used to identify locations on the map. It is made of latitude and longitude lines. The latitude lines are also called parallels and they run west to east. Longitude lines, also known as meridians, run north to south.
The imaginary lines running from north to south on a map are called longitude.

Longitude are the vertical lines found in a map or globe while latitude are the horizontal lines.
A topographic map.
Those lines indicate latitude and longitude, a means of measurement.
