← GeographyWhich phenomenon forms flowstone formations inside limestone caves?
A)Calcium carbonate supersaturation✓
B)Oxidation of iron compounds intrusion
C)Silica gel polymerization flow
D)Cryogenic ice crystal segregation
💡 Explanation
Stalactites and flowstone occur because cave water becomes supersaturated with calcium carbonate as dissolved CO2 escapes during the Degassing process; therefore, CaCO3 precipitates continuously, rather than other metal salts, because limestone is calcium-based.
