What are places where meridians and parallels cross known as?

The correct choice reflects the concept of coordinates, which are defined by the intersection of meridians and parallels on a globe. Meridians are the lines of longitude that run from the North Pole to the South Pole, while parallels are the lines of latitude that run horizontally around the Earth. The specific coordinates of a location are determined by the precise intersection of these lines, expressed in degrees of latitude and longitude.

This system allows for a universal geographic framework that provides a consistent way to pinpoint locations anywhere on the planet. By using coordinates, one can easily identify and communicate specific geographical positions.

Understanding this concept is crucial for air traffic control since precise location identification is essential for navigation, coordination, and communication in aviation.
