← GeographyWhich long-term outcome results when construction prevents deep soil horizon bioturbation by earthworms?
A)Increased surface albedo fraction
B)Decreased subsurface water permeability✓
C)Elevated atmospheric methane production
D)Reduced net primary productivity inland
💡 Explanation
Decreased permeability develops because earthworm bioturbation normally creates macropores that enhance drainage; therefore, reduced bioturbation from soil compaction decreases water infiltration rates, rather than impacting albedo or methane production.
