Differentiate between azimuth and bearing in land navigation.

• A. An azimuth is the distance to a target; a bearing is elevation.
• B. Azimuth and bearing are interchangeable terms with no difference.
• C. Azimuth is a clockwise angle from north to a target; bearing is the direction to a target expressed in degrees relative to north.
• D. Azimuth is the map legend; bearing is a compass rose.

Answer: (C)

In land navigation, directions are described using angles relative to north. An azimuth is the clockwise angle from north to the line pointing at the target, usually measured 0 to 360 degrees. A bearing describes the direction to a target, expressed as degrees relative to north. So saying the azimuth is a clockwise turn from north and the bearing is that same direction described in degrees from north matches how these terms are used in practice. Distance to a target would be range, not azimuth or bearing, and elevation refers to the vertical angle, not the horizontal direction. Azimuth and bearing relate but are not identical terms, and tools like a map legend or compass rose are features used to interpret direction, not definitions of these concepts.
