Which of the following is NOT a type of North used in map reading?

• A. True North
• B. Grid North
• C. Magnetic North
• D. Geographic North

Answer: (D)

Understanding how “north” is defined in map reading helps explain why the correct answer is the one that isn’t treated as a separate reference. In navigation and cartography, there are three practical north references: True North (geographic north toward the North Pole), Magnetic North (the direction a compass points, which shifts with location and time due to the Earth’s magnetic field), and Grid North (the direction along the grid lines of a map projection, which depends on the map’s coordinate system and can differ from True or Magnetic North). Geographic North is essentially another way to refer to the direction toward the geographic North Pole, which is the same as True North. Because it doesn’t provide a distinct reference direction apart from True North, it’s not listed as a separate category of north used in map reading. So the option that isn’t a distinct type of north in practical map navigation is Geographic North.
