Locating Places on the Earth
Maps and globes help us represent the curved surface of Earth and locate places precisely. This chapter builds the language of location: directions, symbols, scale, latitudes, longitudes, hemispheres, and coordinates. These tools are useful not only in geography but also in travel, disaster response, weather studies, navigation, and understanding the relationship between places.
Learning Objectives
- •Use cardinal directions and map symbols
- •Explain why scale is needed on a map
- •Distinguish latitudes from longitudes
- •Use a pair of coordinates to locate a place
Key Concepts
A map is a model
A map simplifies reality so that selected information can be shown clearly for a purpose.
Latitude measures north and south
Latitudes are imaginary lines parallel to the Equator and help describe how far a place lies north or south.
Longitude measures east and west
Longitudes run from pole to pole and help describe how far a place lies east or west of the Prime Meridian.
Coordinates work together
Latitude and longitude used together identify a more precise location than either measurement alone.
Terminology
Historical Insight
Finding a school on a map
A legend explains symbols, a scale estimates distance, and a grid or coordinates helps locate the school.
Why time zones exist
Earth’s rotation means places at different longitudes experience local noon at different times; longitude is therefore connected to timekeeping.
Quick Check

How to use this lesson
Read the overview first, then explain the main idea in your own words before checking the key concepts. Use the quick-check questions without looking at the answer.
