Question 1.
What is diffusion?
Show hintHide hint
Think about how smells spread in a room.
Question 2.
When does resuspension occur?
Show hintHide hint
Consider scenarios like waves or stirring.
3Question 3.
What is the primary process by which chemicals move within sediments?
- Evaporation
- Diffusion
- Condensation
Show hintHide hint
Recall how substances spread in liquids.
4Question 4.
True or False: Resuspension can lead to increased turbidity in water.
- True
- False
Show hintHide hint
Think about muddy waters in rivers after a storm.
Question 5.
Propose a model for estimating the combined effects of bioturbation and diffusion on contaminant transport. Explain factors to consider and potential equations.
Show hintHide hint
Think about how each factor influences movement within the sediment.
Question 6.
Design an experiment to measure the impact of resuspension on water quality in a lake. What parameters would you monitor?
Show hintHide hint
Consider how changes in these parameters would reflect the health of the aquatic ecosystem.
