Which North type is indicated by the map grid lines?

• A. True north
• B. Magnetic north
• C. Grid north
• D. None of the above

Answer: (C)

Map grid lines define grid north—the direction along the map’s north–south grid axis. This differs from true north, which points toward the geographic North Pole, and from magnetic north, the compass direction affected by Earth's magnetism. The grid is a separate coordinate system laid over the map, so the direction indicated by the grid lines is grid north, not the true geographic north or the magnetic north. Therefore, the grid lines indicate grid north.
