← GeographyWhich effect arises when increased surface exposure accelerates weathering?
A)Enhanced sediment transport downstream✓
B)Decreased rates of tectonic subsidence
C)Reversal of magnetic field orientation
D)Formation of large igneous provinces
💡 Explanation
Increased exposure enhances weathering, triggering surficial removal; this causes enhanced sediment transport, a negative feedback loop of weathering rather than a mitigation, because more material becomes available. Therefore, the exposed soil is eroded; new surfaces are destabilized.
