What term describes a map feature that is formed by gradicule tick marks and is defined by 2.5 minute tick marks?

• A. Sector
• B. Meridian
• C. Parallel
• D. Graticule

Answer: (A)

Graticule describes the grid of latitude and longitude lines on a map. It’s formed by tick marks that indicate angular distances, typically shown as degrees, minutes, and seconds. When the grid is defined by 2.5-minute tick marks, the lines of latitude and longitude are spaced every 2.5 minutes of arc, creating a precise network to locate coordinates. A meridian is one north–south line of longitude, a parallel is one east–west line of latitude, and a sector is a wedge-shaped region; none of those form the full grid. So the feature formed by the gradicule tick marks and defined by 2.5-minute marks is the graticule.
