On a map, what do the lines labeled with 101° and 48° represent?

• A. Elevation and Depth
• B. Longitude and Latitude
• C. Distance and Time
• D. Geographical Regions

Answer: (B)

The lines labeled with 101° and 48° on a map represent longitude and latitude, respectively. Latitude lines are defined in degrees north or south of the Equator, while longitude lines indicate degrees east or west of the Prime Meridian. When interpreting these lines, the number indicating latitude (like 48°) provides information about how far north or south a point is relative to the Equator, whereas the number indicating longitude (like 101°) describes how far east or west a point is in relation to the Prime Meridian. This coordinate system is fundamental to navigation and cartography, facilitating accurate positioning on the globe. Understanding this system is essential for pilots, navigators, and anyone working within the National Airspace System, as it helps to ensure safe and efficient routing of aircraft and management of air traffic.
