← GeographyWhich consequence accelerates alabaster cave formation via sulfuric acid?
A)Increased microbial sulfate oxidation✓
B)Decreased atmospheric carbon dioxide
C)Elevated ambient cave temperature
D)Reduced groundwater flow pressure
💡 Explanation
Increased microbial sulfate oxidation produces sulfuric acid which enhances dissolution of limestone because the acid reacts with calcium carbonate. This accelerates cave formation; therefore high microbial activity speeds up the process, rather than slowed oxidation under changed conditions.
