What is the best illustration of the concept of absolute location?

The best illustration of the concept of absolute location is represented by the coordinates provided for Phoenix, which are latitude 33 degrees 45 N and longitude 112 degrees 08 W. Absolute location refers to a specific point on the Earth's surface defined by a coordinate system such as latitude and longitude. This system offers a precise location that can be universally understood regardless of other geographical context. The numbers given correspond to exact positioning on a map, allowing anyone to pinpoint Phoenix exactly, no matter where they are in the world.

In contrast, the geographical center of the United States, while informative, does not provide a specific location applicable to an individual place like Phoenix; it relates to a broader area. Using relative terms like "near" and "far" gives a subjective description of locations and does not define a location precisely, hence it does not qualify as absolute. Lastly, describing Chicago based on its time zone takes into account the region's relationship to time rather than relying on exact coordinates, which again detracts from the definition of absolute location.
