← GeographyWhich outcome occurs regarding speleothem deposition when water evaporation increases within caves?
A)Increased stalactite precipitation rates✓
B)Decreased calcite saturation levels
C)Reduced depositional layer thickness
D)Enhanced aragonite crystal formation
💡 Explanation
Elevated evaporation causes increased stalactite precipitation rates through carbonate supersaturation; the process, called mineral precipitation, occurs because dissolved ions combine into solid form as the water loses its solvent capacity; therefore calcium carbonate deposits faster, rather than reduced thickness through slower evaporation cycles.
