← GeographyWhich risk increases along fault lines traversing alluvial plains?
A)Increased liquefaction during seismic activity✓
B)Accelerated chemical weathering of bedrock
C)Decreased sediment deposition rates
D)Reduced groundwater recharge rates
💡 Explanation
Increased liquefaction occurs because seismic waves cause saturated, unconsolidated alluvial sediments to lose strength via pore pressure increase; therefore, ground fails more readily during shaking, rather than remaining stable due to bedrock integrity or faster drainage.
