The most important lines of longitude and latitude are the equator, the prime meridian, tropic of Cancer, tropic of Capricorn and the international dateline.
Longitude . . . 87.7210° West
Latitude . . . 42.0363° North
Longitude lines go vertically and latitude lines go horizontally.
Most maps will show latitude and longitude lines, if not, they're ALWAYS on a globe.
Probably the longitude and latitude lines because they help you locate countries and cities.
The North/South lines on the geographic grid are named 'Lines of Longitude' or 'Meridians'. The 'Zero' line passes through Greenwich Observatory in London, England. This position was fixed historically, some 350 years ago, by Astronomers and navigators of the day, and has remained so to this day. The 180 degrees line of longitude passes through the Pacific Ocean, and for most of its course it is also the International Date Line.
probably the latitude and the longitude
A 'line' can be drawn on a map or globe at any longitude or any latitude.There is no standard set of 'lines'.To me, I'd say the most important ones are the parallel of 42.0363° north latitudeand the meridian of 87.7208° west longitude, since those are the ones that bringme [close to] home at night.
Latitude and longitude are angles, and can be expressed in any angle unit. The 'degree' and its sub-divisions have always been the most popular.
Germany is a rather large place. The northern most point of Germany is at Latitude 54.908199, Longitude 8.651733. The southern most point is at Latitude 47.275502, Longitude 10.184326. The western most point is Latitude 51.053481, longitude 5.869446. The eastern most is Latitude 51.272226, Longitude 15.04097.
They're used equally. With only one of them it's like trying to find the right house when you know the street name, but not the number.
The lines aren't measured at all, any more than the marks on a ruler need to be.It's the latitude and longitude that need to be measured, and lines are oftenprinted on maps in order to make the job easier. Latitude and Longitude are angles,so they're described in angle units, most commonly in degrees and fractions of degrees.If you see a line on a map, every point on the 'line' has the same latitude or the samelongitude, so there's nothing on the line to measure.
the five major lines of longitude are the greenwich meridian,yellowich meridian, bluewich meridian, orangewich meridian and the pinkwich meridian * * * * * The major longitude is the Greenwich meridian. The other is the line of longitude on the opposite side of the earth - more or less the International Date Line. Except that it is not a straight pole-to-pole line.
Latitude and longitude are simply the way we can describe any point on the surface of the Earth. It's easy to use and easy to understand, and it's already printed on most maps.
