19.6.2. Atmometer (Evaporimeter)

Try these first

1. 1.

   What does an atmometer measure?

   Hint

   Think about what kind of process involves the loss of water to the atmosphere.

2. 2.

   True or False: Atmometers are complex devices that require extensive technical knowledge to operate.

   Hint

   Consider the context in which farmers might use this instrument.

3. 3.

   What primary function does the atmometer serve?

   • Measure pressure
   • Measure humidity
   • Measure evaporation

   Hint

   Think about what aspect of the water cycle it pertains to.

4. 4.

   True or False: The atmometer directly measures transpiration rates of plants.

   • True
   • False

   Hint

   Consider the distinction between evaporation and transpiration.

5. 5.

   A farmer notices the atmometer shows unusually high evaporation rates in July. Outline potential changes to their irrigation strategy.

   Hint

   Consider how high evaporation could influence water availability and plant needs.

6. 6.

   If the materials used in an atmometer are changed, how might that affect the accuracy of measurements? Discuss possible implications.

   Hint

   Think about how changing the components impacts the water evaporation process.
