What causes sinkholes to form?

Sinkholes form when underground water dissolves soluble rocks like limestone, gypsum, or salt, creating voids beneath the surface. Over time, the ground above collapses into these voids, creating a sinkhole. Heavy rainfall, groundwater withdrawal, or construction activity can accelerate the process. Sinkholes vary in size and can cause significant damage to infrastructure and ecosystems. Understanding the geology of an area is crucial for identifying and mitigating sinkhole risks.
