Now you know that well-designed maps have certain features such as a title, date, legend, compass rose, and a scale to make them easier to understand. The scale of a map is an important tool for recognizing the relationship between the size of a map and the actual size of the place the map represents. Imaginary lines of latitude and longitude help determine the exact location of places on Earth, and the rotation of Earth on its axis causes different time zones in different longitudes.
