What is the purpose of latitude and longitude in geography?

• A. Measure population density.
• B. Indicate climate zones.
• C. Provide a precise coordinate system that pinpoints a specific place on Earth's surface.
• D. Determine time zones.

Answer: (C)

Latitude and longitude create a global coordinate grid that uniquely identifies any location on Earth. Latitude lines run east–west and measure how far north or south a place is from the equator. Longitude lines run north–south and measure how far east or west a place is from the Prime Meridian. By giving a place a specific pair of coordinates, you can pinpoint its exact position on the globe, which is why this system is essential for maps, navigation, and GPS.

Think of it this way: coordinates are like a precise street address for any point on Earth. Population density describes how many people live in an area, which is about distribution, not exact location. Climate zones relate to weather patterns that correlate with latitude but aren’t single coordinates. Time zones are regions set by human decisions, though they often align with longitude, but they’re not what you use to locate a place.
