Which map element shows the orientation of north?

The north arrow is a crucial element on a map that indicates the direction of north relative to the map's orientation. It typically features an arrow pointing towards the north and often includes markings to denote other cardinal directions (east, south, west). Understanding the direction of north is essential for interpreting map features accurately, navigating the terrain, and relating the map to real-world geography.

Other elements, such as the scale bar, legend, and grid lines, serve different purposes. The scale bar provides a reference for distance, the legend explains symbols used on the map, and grid lines help establish coordinates. However, none of these elements serve to directly indicate the orientation of north, making the north arrow the clear choice for this function.
