1.1. The Hydrologic Cycle

Try these first

1. 1.

   What is evaporation?

   Hint

   Think about what happens when the sun heats water.

2. 2.

   Name the process by which plants release water vapor.

   • True
   • False

   Hint

5. 5.

   Assuming a specific area experienced a 40% increase in rainfall over a period. How would this impact the processes of infiltration and runoff?

   Hint

   Consider how saturated soil behaves with additional rain.

6. 6.

   Calculate the total volume of water that infiltrates into groundwater during a year, given that a region has an average precipitation of 500mm, and assumes 30% of that infiltrates.

   Hint

   How do units convert when you’re working with volume?
