How Sinkholes Open Up Without Warning Beneath Solid Ground
What A Sinkhole Really Is: A sinkhole is a hole in the ground that forms when the surface layer collapses into empty space below. Many sinkholes happen suddenly, making them dangerous for roads, homes, cars, and even people. While some sinkholes are small, others can grow large enough to swallow buildings or sections of highways. Most sinkholes form in areas where water slowly dissolves rock beneath the ground. This process creates underground spaces that may stay hidden for years before the surface suddenly caves in.
