Which outcome occurs when rapid groundwater extraction increases?

💡 Explanation

An increased frequency of sinkholes occurs when rapid groundwater extraction takes place; this is due to the mechanism of effective stress reduction. Because the pore water pressure decreases, the effective stress on the soil increases, and therefore less support is available, resulting in collapse rather than stability.
