Show hintHide hint
Think about concentration gradients.
Question 2.
What is resuspension?
Show hintHide hint
Consider disturbances like rain or winds.
3Question 3.
What is the primary mechanism of chemical transport from sediments to water?
- Advection
- Resuspension
- Diffusion
Show hintHide hint
Remember the D in DRS stands for diffusion.
4Question 4.
True or False: Bioturbation slows down the transport of chemicals in sediments.
- True
- False
Show hintHide hint
Consider how living organisms interact with sediment.
Question 5.
Model the effect of increased storm intensity on the rates of diffusion and resuspension in a lake sediment environment.
Show hintHide hint
Think about how storms disturb the sediment and affect chemical exchanges.
Question 6.
Evaluate the long-term effects of bioturbation on sediment quality and related water quality parameters.
Show hintHide hint
Consider both positive growth effects and negative pollutant transport implications.
