Which statement best describes North references: True North, Magnetic North, and Grid North?

• A. True North is toward the geographic North Pole; Magnetic North is indicated by a compass; Grid North aligns with map's vertical grid lines.
• B. True North is indicated by compass; Magnetic North toward North Pole; Grid North along longitude lines.
• C. True North equals Magnetic North; Grid North equals True North.
• D. True North is random; Magnetic North fixed; Grid North always 90 degrees from True North.

Answer: (A)

Understanding the three ways we reference north is essential for navigation and map reading. True North points toward the geographic North Pole—the direction along the earth’s axis. Magnetic North is the direction a compass needle points, pulled by the Earth’s magnetic field, and it moves over time as the field shifts. Grid North is the direction along the grid lines on a map—the orientation of the map’s own coordinate system.

The best description combines these ideas: True North is toward the geographic North Pole, Magnetic North is indicated by a compass, and Grid North aligns with the map’s vertical grid lines. This captures the distinct meanings: geographic direction for True North, magnetic direction for Magnetic North, and map-based direction for Grid North.

Why the other statements don’t fit: True North is not indicated by a compass (that’s Magnetic North), and Grid North isn’t universally defined as along longitude lines or always 90 degrees from True North; those specifics depend on map projection and grid orientation. Similarly, True North and Magnetic North are not the same, and Grid North isn’t inherently fixed relative to True North.
