The set of latitude and longitude lines that form a grid on a map is called what?

• A. Contour
• B. Legend
• C. Geographic Grid
• D. Scale

Answer: (C)

Maps use a geographic grid to locate positions anywhere on Earth. The set of latitude lines, which run east-west and measure distance north or south from the equator, together with longitude lines, which run north-south and measure distance east or west from the prime meridian, creates a coordinate system that lets you specify exact places. This grid provides a universal reference frame for navigation, GPS, and spatial analysis. Other map features serve different purposes: contour lines show elevation, a legend explains symbols, and a scale shows how map distances translate to real distances; none of these form the global coordinate grid.
