Which outcome occurs when excessive agricultural irrigation destabilizes poorly consolidated loess deposits?

💡 Explanation

Liquefaction risk increases due to saturation triggering a sudden decrease in effective stress within the loess during seismic activity, making the soil behave like a liquid because the Grain Fabric Collapse mechanism is activated; therefore, soil liquefaction occurs, rather than other effects from consistent moisture conditions.
