In which direction do lines of longitude run?

• A. East to West
• B. North to South
• C. Diagonal
• D. Circular

Answer: (B)

Lines of longitude run from pole to pole, that is, from the North Pole to the South Pole. They’re the meridians used to measure how far east or west a location is from the Prime Meridian. On maps they appear as vertical lines that stretch top to bottom and cross lines of latitude at right angles. Because they connect the poles, their direction is north–south. By contrast, lines of latitude run east–west and circle the globe parallel to the equator.
