Latitude lines direction combines which two elements correctly?

• A. East-west, measure north/south
• B. North-south, measure east/west
• C. Up-down, measure vertical
• D. Diagonally, measure distance

Answer: (A)

Latitude lines are horizontal circles around the globe, so they run east-west. The numbers assigned to latitude tell you how far north or south you are from the equator, meaning they measure north/south position. This is why the description “east-west, measure north/south” fits: the lines stretch left to right, and their values indicate distance north or south from the equator. In contrast, longitude lines run north-south and measure east/west position, so they wouldn’t describe latitude. Vertical or diagonal terms don’t apply to how latitude is defined.
