Geographic coordinates for charted objects are expressed as which pair?

• A. Latitude and longitude
• B. Bearing and range
• C. Depth and temperature
• D. Time and date

Answer: (A)

Geographic coordinates identify a location on the Earth's surface using two angular measurements. Latitude measures distance north or south of the equator, ranging from 0° at the equator to 90° at the poles. Longitude measures distance east or west of the Prime Meridian, ranging from 0° to 180°. Together, they form a pair that uniquely specifies a point on a chart. Typically you see latitude listed first, then longitude, and you can express them in degrees, minutes, seconds or decimal degrees. This pairs uniquely distinguishes positions, unlike bearing and range (direction and distance from a reference point), depth and temperature (environmental measurements), or time and date (temporal information). Hence, geographic coordinates are expressed as latitude and longitude.
