Which statement best explains why controlling sulfur dioxide emissions alone may not completely solve acid-deposition problems?
Nitrogen oxides and other contributing compounds can continue to generate acidic deposition even when sulfur dioxide declines.
0%
Sulfur dioxide has no relationship to acid deposition.
0%
Acid deposition occurs only through dry particles and therefore cannot be controlled through emission reductions.
❌
Acid deposition is controlled entirely by carbon dioxide.

Why is groundwater contamination especially difficult to manage?
Groundwater pollution is always visible before it becomes hazardous.
0%
Groundwater may be renewed slowly, allowing pollution to persist, while cleanup is technically difficult and expensive.
✅
Groundwater moves so rapidly that pollutants cannot be located.
0%
Groundwater is naturally sterile and therefore cannot degrade contaminants.

✅
Prevents sunlight from initiating atmospheric reactions.
0%
Converts all primary pollutants into harmless compounds.
0%
Accelerates vertical mixing of polluted air.
