Question 1.
What does ET₀ stand for?
Show hintHide hint
Think about what measures the water loss from crops.
Question 2.
Name one factor affecting evapotranspiration.
Show hintHide hint
Consider environmental conditions.
3Question 3.
What is the main purpose of the FAO Penman-Monteith Equation?
- To calculate rainfall
- To estimate reference evapotranspiration
- To measure soil moisture
Show hintHide hint
Consider what it measures in relation to water loss.
4Question 4.
True or False: Vapor Pressure Deficit (VPD) affects the rate of evapotranspiration.
- True
- False
Show hintHide hint
Think about moisture levels affecting evaporation.
Question 5.
A region records Rn = 20 MJ/m²/day, G = 0.1 MJ/m²/day, T = 30°C, u_2 = 4 m/s, e_s - e_a = 2 kPa, Δ = 0.15 kPa/°C, and γ = 0.067 kPa/°C. Calculate ET₀ using the FAO Penman-Monteith Equation.
Show hintHide hint
Substituting values into the equation step by step will yield the correct answer.
Question 6.
Discuss how potential evapotranspiration (PET) might differ during summer versus winter in a temperate climate.
Show hintHide hint
Consider how temperature influences water evaporation rates throughout the seasons.
