Which tools help readers locate places and measure distance on maps?

• A. Temperature and precipitation
• B. Latitude and longitude, and map scales
• C. Time zones and daylight hours
• D. Population density and urbanization

Answer: (B)

This question hinges on how maps help you find locations and judge distance. Latitude and longitude provide a global grid that lets you pinpoint any place precisely by coordinates. Think of it as a universal address system: lines of latitude run east–west to show how far north or south you are, and lines of longitude run north–south to show how far east or west you are. With those coordinates, you can locate a city, landmark, or any point on any map or globe.

Map scales are what translate the distance you see on the map into real-world distance. They show how much a measured length on the map represents in actual kilometers or miles. So you can compare how far apart two places are by measuring on the map and converting using the scale.

Other options describe climate data, time-related information, or how people are distributed, none of which directly help you locate places or measure distance on a map.
