F. Isolines Isolines are used to show the occurrence of features/phenomena that are present everywhere in a given area, but in varying quantities from place to place – for example, area temperature.

9. Isolines have all the properties EXCEPT the following: a. They are always closed loops (even though the loop may close outside the map area). b. They may cross each other. c. The numerical difference between isolines are intervals. d. Close isolines indicate a steep gradient.
