You can, but the distances are not constant - they are zero at the poles and increase as you go towards the equator.
You may be thinking of the distance between lines of longitude. The length of the lines of latitude decrease because the Earth is round, so the length of the line is shorter at the poles than it is at the Equator. The distance between the lines of longitude is shorter as you move toward the poles, again, because the Earth is round. All lines of longitude are the same length.
It depends on one's latitude, I believe. Distance at the Poles, Zero, at the Equator about 700 miles.
A ruler
No but parallel lines have a constant distance between them
Because all of the longitudes converge in a single point, at both the north andsouth poles. When you stand at a pole, you're standing on every longitude.
Lines of longitude are vertical but they measure horizontal distance(In degrees,not kilometers or miles)between Greenwich Mean Time(GMT) and you so the lines are vertical,not horizontal. However,longitude measures horizontal distance,not vertical distance.
None. The distances between the lines of longitude are a meaningless concept. These lines measure angular distance around the world around the equator. Each degree of longitude is approx 111 km at the equator and 0 km at the poles.
through the Prime Meridian.
None. they are a measure of angular distance and not of linear distance.
All of the other meridians; the lines of longitude.
Longitude measures the distance east and west of the prime meridian.
east and west
Location of a point on the surface of the earth.
They measure east and west
the answer is longitude and latitude lines
east west
