← GeographyWhich risk increases as water evaporates during stalactite formation?
A)Increased mineral concentration at dripping point✓
B)Decreased dissolution rate of limestone
C)Greater drip rate from saturated flow
D)Reduced carbon dioxide absorption into water
💡 Explanation
Increased mineral concentration at the drip point occurs because evaporation enhances supersaturation, driving mineral precipitation via deposition; therefore, increased mineral deposit, rather than decreased dissolution, results from increased mineral concentration.
