16. Summary

Try these first

1. 1.

   What is evaporation?

   Hint

   Think about where water goes when it gets warm.

2. 2.

   Name one factor affecting evaporation.

   Hint

   Consider what happens when the sun is out.

3. 3.

   What is the primary process of transforming liquid water into vapor?

   • Transpiration
   • Evaporation
   • Infiltration

   Hint

   Think of how puddles disappear on a sunny day.

4. 4.

   True or False: Interception contributes to surface runoff.

   • True
   • False

   Hint

   Consider what happens to rain on a leaf.

5. 5.

   Given a field with sandy and clay soils, discuss how you would expect their water retention and infiltration capacities to differ after a rainfall event.

   Hint

   Consider the texture and structure of the soils involved.

6. 6.

   Using the Penman-Monteith Equation, estimate the average evapotranspiration if the net radiation is 500 W/m², soil heat flux is negligible, temperature is 25°C, wind speed is 2 m/s, and vapor pressure deficit is measured at 1 kPa.

   Hint

   Break down the equation into its components and apply values step by step.
