What do vertical lines on a globe measure?

• A. Distance from east to west
• B. Distance from north to south
• C. Elevation above sea level
• D. Temperature

Answer: (A)

Vertical lines on a globe are lines of longitude. They run from the North Pole to the South Pole and tell you how far east or west a place is from the Prime Meridian, which is 0 degrees longitude. Longitudinal positions increase as you move east (up to 180°) and decrease as you move west (up to 180°). This is why these lines measure east–west location. Horizontal lines, by contrast, measure north–south position and are called latitudes. Elevation above sea level is about height, and temperature is a weather measure, not a location coordinate.
