Isotherms

Rules for Isotherms:

1. Draw isotherms in a smooth line, not jagged.

2. Isotherms should begin and end at an edge of the map, or loop around and close on itself.

3. An isotherm should never cross another isotherm, nor should it branch or fork.

4. Isotherms should be drawn at equal intervals.
