Question 1.
What is diffusion?
Show hintHide hint
Think about where molecules prefer to move.
Question 2.
What is advection?
Show hintHide hint
Consider movements caused by a current or wind.
3Question 3.
Which mechanism primarily drives mass transfer in sediments?
- Advection
- Diffusion
- Convection
Show hintHide hint
Remember, diffusion is about concentration differences.
4Question 4.
True or False: Advection always dominates in water systems.
- True
- False
Show hintHide hint
Think about slow-moving environments.
Question 5.
Given a scenario where pollutants were released into a deep lake, analyze their transport over a decade. What will affect their dispersion?
Show hintHide hint
Consider both physical movement and chemical interactions.
Question 6.
Design an experimental setup to measure the diffusion rate of a contaminant in sediments. What factors will you need to consider?
Show hintHide hint
Think about how you would isolate variables in your experiment.
