← GeographyWhich speleothem formation increases when sulfuric weathering dominates limestone caves?
A)Gypsum crust deposition✓
B)Flowstone terrace formation
C)Calcite raft accumulation
D)Helictite crystal branching
💡 Explanation
Gypsum crust deposition increases with sulfuric weathering because oxidation generates sulfuric acid, reacting with the limestone bedrock via acid dissolution; therefore gypsum forms, rather than formations dominated by calcium carbonate solutions typical in limestone dissolution.
