Question 1.
What is diffusion?
Show hintHide hint
Think about how smells spread in a room.
Question 2.
What does resuspension refer to?
Show hintHide hint
Consider what happens to sediment during a storm.
3Question 3.
What is the main objective of diffusion in sediment?
- To increase concentration
- To move from high to low concentration
- To resist flow
Show hintHide hint
Remember the principles of concentration gradients.
4Question 4.
True or False: Resuspension can pollute water bodies during heavy rainfall.
- True
- False
Show hintHide hint
Consider the effects of storms on sediment integrity.
Question 5.
Given a situation in a lake where a storm causes resuspension of contaminated sediment, what strategies could be employed to mitigate the water quality impact?
Show hintHide hint
Consider both engineering solutions and natural methods.
Question 6.
Model a scenario where bioturbation is affecting chemical transport differently than diffusion alone. What factors might you need to consider?
Show hintHide hint
Think about how bioactivity interacts with environmental conditions.
