← GeographyWhich outcome is observed when subsurface clay layers impede water flow?
A)Stream density channel network increases✓
B)Reduced chemical stream weathering rates
C)Enhanced groundwater recharge locally occurs
D)Decreased floodplain sediment deposition apparent
💡 Explanation
Stream density increases due to impeded infiltration; this confinement forces surface flow (overland flow), therefore increasing channels exhibiting drainage density because the hydraulic conductivity dictates stream networks rather than altering sediment deposition dynamics.
