Question 1.
What is flux in environmental terms?
Show hintHide hint
Think about flow rates.
Question 2.
Define the gradient technique.
Show hintHide hint
It involves comparing concentrations.
3Question 3.
What does the gradient technique help determine?
- Soil pH
- Flux measurements
- Temperature variations
Show hintHide hint
Think about its purpose in environmental studies.
4Question 4.
True or False: The Thornwaite-Holzman equation considers both concentration and turbulent diffusion.
- True
- False
Show hintHide hint
Consider what the equation represents.
Question 5.
Calculate the flux if the concentration of a pollutant at height 1 is 600 µg/m³ and at height 2 is 400 µg/m³ over 10 meters with a diffusion coefficient of 2 m²/s.
Show hintHide hint
Use the gradient formula to solve.
Question 6.
Explain how non-instantaneous concentration measurements could lead to errors in estimating flux.
Show hintHide hint
Reflect on temporal changes in pollutant levels.
