Show hintHide hint
Think about both soil and plant processes.
Question 2.
What is Potential ET?
Show hintHide hint
Consider what would happen if the soil was never dry.
3Question 3.
What does Evapotranspiration encompass?
- Only evaporation
- Only transpiration
- Both evaporation and transpiration
Show hintHide hint
Remember what two processes contribute to ET.
4Question 4.
True or False: Actual ET is always greater than Potential ET.
- True
- False
Show hintHide hint
Think about limits based on available moisture.
Question 5.
A farmer uses tools to measure soil moisture and determines that the Potential ET is 12 mm per day. However, actual ET after a week of dry conditions is only 5 mm per day. Why is it important for the farmer to know this difference in values?
Show hintHide hint
Consider how these measurements influence irrigation needs.
Question 6.
Evaluate the potential impact of climate change on evapotranspiration rates in arid regions. What might be the implications for agriculture?
Show hintHide hint
Think about temperature effects on ET and plant survival.
