What do you call the total system of parallels and meridians that form a network of intersecting lines?

Result
Your answer: —  Â·  Correct: C
Explanation

The total system of parallels and meridians that form a network of intersecting lines on a globe or map is known as a geographic grid [3]. Parallels are lines of latitude that run east-west, parallel to the equator, while meridians are lines of longitude that run north-south, passing through the poles [3]. The intersection of these two sets of lines creates a grid-like structure that allows for the precise pinpointing of any location on the Earth's surface using coordinates [4]. This network is also technically referred to as a graticule in cartography [4]. The grid system is essential for navigation, as it provides a standardized man-made framework for identifying positions based on angular distances from the equator and the prime meridian [2].
