International Date Line; however, it does zig-zag around some political boundaries.
The imaginary line running through Greenwich, England at 0 degrees longitude is called the Prime Meridian. It marks the starting point for measuring longitude and defines the Eastern and Western Hemispheres.
The imaginary line is called the Prime Meridian.
Distance that is measured in degrees east or west of an imaginary line running north and south through the town of greenwich, England.
The international dateline passes through the Pacific Ocean. The international dateline is an imaginary line that is 180 degrees east of the Greenwich Meridian.
Imaginary lines that run north to south are known as lines of longitude. Longitude lines are the imaginary lines running through the Earth between the North and South Poles. They are arbitrary and used for reference so everyone can know where they are in the world. The lines running north and south are called "meridians" or "lines of longitude."
The Greenwich Meridian is an imaginary longitude line running round the earth North, South, North at 0 degrees in the same way that the Equator is an imaginary latitude line running round the earth.
For exactly the same reason that imaginary labels such as "Mulberry Street" and "416 South" are used. Their purpose is to facilitate the description of locations ... for the convenience of both the people who are already there and wish to describe their whereabouts, and the people who are presently elsewhere who wish to journey to that place. Note that 'latitude' and 'longitude' are not lines. They are angles. If you mark a million different points on the Earth's surface that ALL have the same latitude, or all have the same longitude, THEN the points begin to resemble a line.
A longitude line does not "land" on a continent as it is an imaginary line. However, 15 degrees East longitude passes through the continent of Europe, running through countries such as France, Germany, and Italy.
Longitude lines are a set of imaginary lines that goes around the earth over the poles. The Prime Meridian is the longitude line that divides the earth into the eastern and western hemispheres, just as the equator divides the northern and southern hemispheres.
The imaginary line that divides the Earth into east and west longitude is called the Prime Meridian. It is located at 0 degrees longitude and passes through Greenwich, London, UK.
