← GeographyWhich outcome is accelerated when the drip rate increases impacting cave stalactite formation?
A)Increased localized calcium carbonate supersaturation
B)Decreased water film thickness on stalactite✓
C)Enhanced carbon dioxide dissolution in water
D)Diminished laminar flow from solution seepage
💡 Explanation
Increased drip rate accelerates the **thin-film evaporation** rate from the stalactite surface, because the residence time for water decreases. This lowers film thickness, therefore increases deposition efficiency from solution, rather than enhancing dissolution or CO2 uptake which require longer contact.
