Longitude and latitude are imaginary lines that circle the Earth. They are used to exactly pinpoint where a person or object is located. These lines are on maps and measured in degrees. Each degree is divided into 60 minutes, and each minute has 60 seconds.

Because the Earth rotates around its axis once a day, it is divided into 24 different time zones.
