* Latitude defines a circle: Latitude lines run parallel to the equator, creating circles around the globe. A specific latitude value defines a whole circle, not a single point.
* Longitude is needed: To pinpoint a specific location, you need both latitude and longitude. Longitude lines run from the North Pole to the South Pole, intersecting the latitude circles. The intersection of a specific latitude and longitude is the unique location of a place.
Example:
* Latitude 40° N could represent anywhere along the circle that is 40 degrees north of the equator. This could be in North America, Europe, Asia, or even the ocean.
* Longitude 74° W could represent anywhere along the line that is 74 degrees west of the Prime Meridian.
* The combination of Latitude 40° N and Longitude 74° W pinpoints a specific location, which is somewhere near New York City.
