2. 2.

   List two factors that influence evaporation.

   Hint

   Consider natural elements that affect water.

3. 3.

   What is evaporation?

   • The process of raining
   • Water changing from liquid to vapor
   • Water freezing

   Hint

   Think about what happens to puddles when the sun shines.

4. 4.

   True or False: Evaporation does not affect climate models.

   • True
   • False

   Hint

   Consider the role of water in weather changes.

5. 5.

   Given a reservoir that loses 100 square meters of water daily due to evaporation, calculate the annual water loss caused by evaporation.

   Hint

   Think about multiplying the daily loss by the number of days in a year.

6. 6.

   In a moderate climate, if the average evaporation rate is calculated to be 5mm/day, what is the total volume of water evaporated from a lake with an area of 1 hectare over one month?

   Hint

   Don’t forget to convert mm to meters for the calculation!
