Time zones are imaginary lines
In general, an imaginary line is usually any sort of geometric line that has only an abstract definition and does not physically exist. In fact, they used to properly identify places on a map.
Some outside geography do exist, such as the Mendoza Line, which in baseball divides below-average hitters and extremely poor hitters. A centerline is a nautical term for line down the center of a vessel lengthwise.
Examples
Geography
As a geographical concept, an imaginary line may serve as an arbitrary division, such as
- Antarctic Circle,
- Arctic Circle,
- Border,
- International Date Line,
- Latitude, including the Equator,
- Longitude, the prime meridian, the Tropic of Capricorn and the Tropic of Cancer.[1] Any axis about which an object spins is an imaginary line.
- Mason–Dixon line, which informally marks pieces of the borders of four U.S. states: Delaware, Maryland, Pennsylvania, and West Virginia, once part of Virginia. Symbolically, the line separates the American North from the American South,
- Missouri Compromise Line,
- Time zones.
Science and engineering
- Line of sight
- Optical ray
- Force lines in mechanical and structural engineering
- Field lines for electric and magnetic fields
