From what I can remember, the latitude line located at 0 is the meridian line. But I can be wrong
Longitude is the best term, but sometimes meridian is used. The line of longitude at zero degrees is the Prime Meridian.
Lines of longitudes are also called Meridians. These vertical lines are drawn from the North to South poles.The meridian through Greenwich, England, called the Prime Meridian, was set at zero degrees of longitude. The meridian on the opposite side of the earth from Greenwich is called the International Date Line (IDL), which is at roughly 180° longitude.
Imaginary lines that circle the earth from east to west are called lines of longitude, or meridians. These lines help define the distance east or west of the prime meridian, which is located in Greenwich, England.
Meridians of longitude; parallels of latitude. Remember that meridians are all the same length (20,000 km) and that they meet at the poles. Parallels are, well, parallel, and are different lengths, the longest being the Equator.
Parallels and meridians. Circles parallel to the Equator (lines running east and west) are parallels of latitude. They are used to measure degrees of latitude north or south of the Equator. Meridians of longitude are drawn from the North Pole to the South Pole and are at right angles to the Equator.
The imaginary semi-circular "lines" of constant longitude are "meridians". The imaginary full-circular "lines" of constant latitude are "parallels".
meridians
Meridians of longitude run north and south. Parallels of latitude run east and west.
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.
Meridians.
Yes, lines of longitude are also known as meridians. For example: 0° longitude is the the prime meridian.
lines of latitude are parallels and lines of longitude are meridians. latitude lines are circles around the earth running east west (like equator) longitude lines run north - south and they meet at two spots, the north pole and the south pole. Meridians also determine the time at a location on the earth.
