Show hintHide hint
Remember the direction of movement is based on concentration gradients.
Question 2.
What is bulk flow?
Show hintHide hint
Think about how water moves in rivers!
3Question 3.
What is the primary mechanism of pollutant transport in unsaturated soils?
- Bulk Flow
- Molecular Diffusion
- Evaporation
Show hintHide hint
Consider the role of water in these zones.
4Question 4.
True or False: Advection is synonymous with molecular diffusion.
- True
