Try these first

1. 1.

   What is an isohyet?

   Hint

   Think about how we represent equal amounts on a map.

2. 2.

   What is the main purpose of the Isohyetal Method?

   Hint

   Consider how we might visualize different amounts of rain.

3. 3.

   What is the main function of isohyets?

   • To measure rainfall
   • To connect points of equal rainfall
   • To predict weather patterns

   Hint

   Consider what joining these points achieves.

4. 4.

   True or False: An isohyet can help determine the average rainfall for a large area.

   • True
   • False

   Hint

   Think about the representation of area on a map.

5. 5.
