← GeographyWhich landscape transformation accelerates after extensive soil bioturbation?
A)Enhanced sediment weathering rates✓
B)Increased floodplain sedimentation
C)Reduced carbon sequestration totals
D)Decreased soil aggregation overall
💡 Explanation
Bioturbation mixes soil, exposing more surface area; this accelerates chemical weathering because increased surface interactions occur. Therefore, weathering increases, rather than reduced carbon storage or simple sediment deposition, given the increased soil reactivity.
