ace1o1 · #2That is freaking creepy....I wonder how they occurred and how many more there are out there...Sinkholes occur when the ground beneath is rich in easily dissolved rocks such as limestone, carbonates and salt beds. When groundwater flows through these rocks, it eats away at them, leaving behind subterranean holes and caverns. When the roof of one of these caverns collapses, it takes the land above down with it. They are most common Florida, Texas, Alabama, Missouri, Kentucky, Tennessee and Pennsylvania, especially if caves are found like Mammoth Cave in Kentucky is riddled with sinkholes.
