What do longitude lines run, and what do they measure?

• A. Longitude lines run north-south and measure east-west from the Prime Meridian.
• B. Longitude lines run east-west and measure distance north-south from the equator.
• C. Latitude lines run north-south and measure east-west.
• D. Latitude lines run north-south and measure time zones.

Answer: (A)

Longitudes are lines that run from the North Pole to the South Pole. They measure how far east or west a place is from the Prime Meridian, the zero-degree reference line that passes through Greenwich, England. So longitudes run north–south and indicate east–west position relative to that meridian. By contrast, lines of latitude run east–west and tell you how far north or south a location is from the equator.
