3. 3.

   What is the primary function of an isopluvial map?

   • To show temperature variations
   • To show rainfall depth or intensity
   • To display geographical borders

   Hint

   Think about the measurements we discussed.

4. 4.

   Is it true that isopluvial maps can help estimate design storms in places with no gauges?

   • True
   • False
