Answer:
A:A. Indicates cardinal and intermediate directions on a map.
Step-by-step explanation:
A map grid is a set of horizontal and vertical lines that are drawn over a map and represent the cardinal directions (north, south, east, west). These lines are very useful for the work of geologists and cartologists because it allows certain regions to be found using the lines as a reference. For this, it is necessary to find a point on the map, which is the location that is referenced, locate the lines closest to that point and calculate the "square" formed between them.
