Which outcome occurs when carbon dioxide saturation decreases in limestone cave seepage?

💡 Explanation

Calcium bicarbonate equilibrium shifts towards CaCO3 because decreased CO2 saturation forces Precipitation, a form of chemical sedimentation, rather than continued carbonic acid erosion; therefore, stalactites form rather than cave widening.

• Which outcome results following increased deposition in river meander?
• Following a volcanic eruption depositing substantial tephra, which outcome initiates accelerated glacial melting downstream?
• Which consequence results when extensive ashfall (tephra) buries grasslands?
• Which phenomenon explains the reduced water salinity near major Amazon river outflow into the Atlantic?
• Which landscape outcome develops because subsurface limestone dissolution accelerates?
• Which risk prominently increases following intense pyroclastic flow events?
