← GeographyWhich consequence results when focused infiltration overwhelms epikarst?
A)Sinkhole formation accelerates rapidly.✓
B)Gouges widen due to corrosion.
C)Caves flood abruptly inland.
D)Nutrient pollution diminishes downstream.
💡 Explanation
Accelerated sinkhole growth occurs because solution weathering widens fractures promoting increased focused infiltration. This positive feedback due to chemical dissolution creates instability. Eventually structural collapse forms sinkholes, therefore, accelerated sinkhole appearance, rather than gouging as stress corrosion creates this, with this process typically exhibiting linearity.
