Question 1.
What is resuspension?
Show hintHide hint
Think about what happens when storms occur in lakes.
Question 2.
Define bioturbation.
Show hintHide hint
Consider how organisms move through the sediment.
3Question 3.
What is total suspended solids (TSS)?
- A measure of dissolved oxygen
- A measure of particulate matter in water
- A measure of sediment temperature
Show hintHide hint
Think about what measurements reflect water clarity.
4Question 4.
True or False: Bioturbation only occurs in freshwater systems.
- True
- False
Show hintHide hint
Consider where organisms might live.
Question 5.
Explore a case where sediment disturbances led to a pollutant spike in a river system after flooding. What were the causes and the long-term implications?
Show hintHide hint
Consider how physical changes from flooding influence sediment behavior.
Question 6.
Develop a model to predict how bioturbation impacts contaminant transport in a lake after a heavy rainfall. Include variables for sediment type and organism density.
Show hintHide hint
Think about how each variable interacts to impact the sediment's behavior.
