Question 2.
Name a type of plume behavior.
Show hintHide hint
Consider the shapes created by pollutant dispersion.
3Question 3.
What happens to pollutants in unstable atmospheric conditions?
- They accumulate
- They disperse upwards
- They remain stagnant
Show hintHide hint
Think about movement during high winds.
4Question 4.
