Which consequence results when excessive groundwater extraction lowers the water table beneath an alluvial aquifer?

A)Increased aquifer compaction and subsidence
B)Enhanced sediment transport to the ocean
C)Accelerated chemical weathering of minerals
D)Decreased frequency of flash flood events

💡 Explanation

Aquifer compaction and subsidence increase because pore water pressure, which once supported the alluvial sediment structure, decreases under the mechanism of effective stress; therefore, the aquifer collapses under increased load, rather than maintaining volume like an unconfined situation.
