20.1. Evapotranspiration – Basic Concepts

Try these first

1. 1.

   Define evaporation.

   Hint

   Think about where water goes when it gets hot.

2. 2.

   What does transpiration refer to?

   Hint

   Consider how plants 'breathe.'

3. 3.

   What is the total water loss from evaporation and transpiration called?

   • Hydration
   • Evapotranspiration
   • Condensation

   Hint

   It starts with 'E' and relates to plants and water.

4. 4.

   True or False: Actual evapotranspiration (AET) can be greater than potential evapotranspiration (PET).

   • True
   • False

   Hint

   Consider if plants can ever use more water than they need.

5. 5.

   Calculate the difference between PET and AET in a scenario where PET is 5 inches and AET is 3 inches. What does this difference indicate?

   Hint

   Think about how much more water could be used compared to what actually is.

6. 6.

   Discuss the potential impacts on ET if the temperature increases by 5 degrees Celsius while the water supply remains constant.

   Hint

   How does temperature affect water use in everyday life, such as when you sweat?
