43.2.2. Components of Consumptive Use

Try these first

1. 1.

   What does consumptive use refer to?

   Hint

   Think about water usage in plants.

2. 2.

   What are the two main processes of consumptive use?

   Hint

   They both involve water moving into the air.

3. 3.

   What are the two components of consumptive use?

   • Evaporation and Transpiration
   • Rainfall and Surface Runoff
   • Infiltration and Percolation

   Hint

   Recall what plants and water surfaces do.

4. 4.

   True or False: Evapotranspiration is simply another term for evaporation.

   • True
   • False

   Hint

   Think about how plants also lose water.

5. 5.

   Given the daily transpiration rates of a crop are 5mm and evaporation rates are 3mm, calculate the total evapotranspiration for the day. How would you adjust irrigation practices based on this data?

   Hint

   Add the amounts and think about what this means for water supply.

6. 6.

   Consider how a rise in temperature could impact both evaporation and transpiration rates in a dry region. Discuss your findings.

   Hint

   Think about the effects of temperature on water cycles.
