its the equator
i belive it is the Prime Merideon!
The Prime Meridian of the world lies at 0˚ longitude.
The lines of longitude are vertical; longitude measures the horizontal distance from 0 degrees longitude. Here is a mnemonic that helps me: Latitude sounds a little like 'ladder-tude', and the rungs of a ladder are horizontal. I picture myself 'stepping up or down' the lines of ladder-tude, and this moves me farther north or farther south. That leaves vertical for longitude. While the lines of longitude are drawn from north to south, their locations measure a parameter that changes from east to west; longitude tells you how far east or west you are (in degrees, not distance) from the prime meridian (zero degrees longitude). Lines of latitude are drawn from east to west, and they measure how far north or south you are. So running the risk of confusing you, the "concept" of longitude (what is your position east/west of the prime meridian) is really horizontal in nature. This can be a little hard to grasp. Draw a line on a piece of paper; make the line exactly one inch from the left margin. You have drawn the line 'up and down', but the line is there to tell you how to get one inch from the margin (left-right) no matter where you are on the paper. And no matter where you are on the line, you are one inch to the right of the left margin. So if you travel up and down a line of longitude, you might cover several thousand miles, but you haven't budged from your measure of longitude-- how far you are (in degrees) from the prime meridian. As you travel along your line of longitude, you see hash-marks with changing numbers of degrees. These are not changes in longitude, but in latitude. They answer: How far north or south am I, along this line of longitude? When doing navigation, the simple thing is that lines of longitude are all long. Since they all go through both the North and South Pole, they are all the same length. Latitude lines vary in length. Latitude: LAT=FLAT Longitude: LONG (heights)
Latitude: -37.81667 Longitude: 144.9667 Latitude (DMS): 37° 49' 0 S Longitude (DMS): 144° 58' 0 E
It depends on the connotation of Prime Meridian. Although there are a number of meridians defined as prime meridians, the Greenwich Meridian was established as the international prime meridian in 1884 and is at 0 degrees longitude. The opposite is 180 degrees longitude. Vietnam is located between 100 and 110 degrees east longitude and between 0 and 25 degrees north latitude. To locate Vietnam using west longitudinal reference it would be between 250 and 260 degrees west longitude. Since the distance from the prime latitude to Vietnam is shorter in the eastward direction than the westward direction it would be considered east of prime meridian.
The prime meridian is a line at 0 degrees longitude.
The prime meridian is a line at 0 degrees longitude.
0 degress latitude is the Equator and 0 degress longitude is the Greenwich Meridian.
0 degrees longitude
longitude
The Prime Meridian is a line of longitude, and it sits at 0 degrees longitude.
"Crossing the Line" is associated with crossing the equator at 0 degrees latitude, not longitude. If you cross the equator (0 degrees latitude) at 0 or 180 degrees longitude, there is an additional status included.
0 degrees latitude is called the Equator. 0 degrees longitude is called the Prime Meridian
The intersection of 0 degrees latitude and 0 degrees longitude is known as the Prime Meridian and the Equator.
The Equator is 0 degrees latitude, and the Prime (or Grenwich) Meridian is 0 degrees longitude.
longitude.
The starting line for measuring latitude is the Equator (0 degrees latitude), while the starting line for measuring longitude is the Prime Meridian (0 degrees longitude), which runs through Greenwich, England.
