What Are Sinkholes? 🌍

Sinkholes occur when the surface layer of the ground collapses into an underground void. This can happen due to various reasons, including:

• Natural Processes: Erosion of soluble rock, such as limestone or gypsum, can create cavities that eventually lead to the formation of sinkholes.
• Human Activities: Construction, drilling, or excessive water extraction can also trigger sinkhole formation.

Understanding sinkholes is essential, as they can pose risks to infrastructure and human safety.
