← GeographyWhich risk increases when groundwater is extracted along an active normal fault?
A)Increased frequency of shallow earthquakes✓
B)Decreased rate of tectonic plate movement
C)Accelerated chemical weathering of rock
D)Reduced geothermal gradient in the crust
💡 Explanation
When groundwater is extracted, reduced pore pressure increases effective stress on the fault because frictional resistance decreases leading to slip events. Earthquakes increase, rather than plate movement changing, weathering accelerating, or heat flow reduction, which involve unrelated pressures and mechanisms.
