Show hintHide hint
Think about what happens to the particles in a muddy river.
Question 2.
Name a natural event that can increase resuspension.
Show hintHide hint
Consider what happens to rivers when it rains a lot.
3Question 3.
What is the primary cause of sediment resuspension in aquatic environments?
- Chemical reactions
- Turbulence in water
- Biological activities
Show hintHide hint
Think about what happens to sediments during a storm.
4Question 4.
True or False: Larger sediment particles will always remain suspended longer than smaller particles.
- True
- False
Show hintHide hint
Consider how particle size affects settling rates.
Question 5.

Show hintHide hint
Consider the cascading effects on organisms at various trophic levels.
Question 6.
Evaluate options for mitigating resuspension impacts in urban rivers prone to flooding. What strategies can be implemented to protect water quality?
Show hintHide hint
