Which outcome increases as groundwater acidity rises during limestone dissolution, creating sinkholes?

💡 Explanation

Increased water acidity accelerates limestone dissolution, expanding subsurface cavities due to chemical weathering; therefore a higher subsidence rate occurs because the ground is less stable, rather than increased flow or decreased regolith.
