← GeographyWhich outcome accelerates stalactite formation when airflow changes?
A)Increased CO2 degassing at meniscus✓
B)Decreased kinetic energy limits deposition
C)Elevated congruent dissolution of calcite
D)Reduced water evaporation equilibrium constant
💡 Explanation
Increased airflow enhances stalactite growth because increased ventilation accelerates CO2 degassing at the water droplet's surface which increases the supersaturation of calcium carbonate and thus carbonate precipitation. Therefore, more calcite is built, rather than dissolved, increasing dimension.
