← GeographyWhich process hinders cave formation within shale layers?
A)Insufficient carbonic acid generation
B)Limited joint and fracture density
C)Elevated shale impermeability levels✓
D)Enhanced calcium carbonate decomposition
💡 Explanation
Cave formation relies on the dissolution of soluble rock; low permeability in shale inhibits water flow via hydraulic conductivity, because water cannot readily penetrate, therefore preventing dissolution of the rock, rather than influencing the acid's production.
