← GeographyWhich process accelerates cave system formation during glacial periods?
A)Eustatic sea level reduction
B)Isostatic crustal rebound
C)Glacial meltwater recharge✓
D)Permafrost aggradation expansion
💡 Explanation
Glacial meltwater enhances cave formation via increased hydraulic gradient that drives solution weathering. This mechanism increases the dissolution where the water table intersects limestone, because meltwater influx is greater rather than the slowing from sea level reduction.
