Differentiate grid coordinates from magnetic azimuths.

• A. Grid coordinates locate a point on a map; magnetic azimuth is a compass bearing relative to magnetic north.
• B. Grid coordinates indicate time; magnetic azimuth indicates distance.
• C. Grid coordinates are used for measuring speed; magnetic azimuth is a terrain feature.
• D. Grid coordinates describe the terrain type; magnetic azimuth describes elevation.

Answer: (A)

Grid coordinates pinpoint a exact location on a map using a grid reference system (like eastings and northings). They tell you where something is on the map, not which way to travel. Magnetic azimuth, on the other hand, is a compass bearing measured from magnetic north. It tells you which direction to move or point to, not a specific spot on the map. In practice you’d use grid coordinates to locate a point and a magnetic azimuth to navigate toward it, sometimes adjusting for magnetic declination to align with true north on the map. The other options mix in time, distance, speed, terrain, or elevation, which aren’t what grid coordinates or magnetic azimuth describe.
