Which risk is increased when excessive groundwater drawdown occurs affecting limestone aquifers?

💡 Explanation

Excessive drawdown lowers the water table, reducing support for overlying soils: groundwater dissolution expands underground cavities, forming sinkholes. Therefore, accelerated sinkhole formation is likely, rather than changes in processes related to coastal, glacial, or deep Earth activities.
