What is a sinkhole? A sinkhole is commonly a rock formation under the surface that dissolves easily and causes all of the land under it to cave in and create a hole in the ground. There is a wide variety of possibilities for a sinkhole to happen but some of the most common possibilities are water underground holding up a thin layer of sediment and when that water moves the rock layers cave in, causing a hole in the ground. Other common possibilities are limestone, carbonate rock, and salt rocks under the surface because they dissolve easily. These are not the only causes for sinkholes but they are some of the most common ones.

The size of the holes can vary from a small hole in your backyard to a mile wide hole going 100 feet deep into the earth. Some sinkholes may not go very deep but cover a lot of land, they all vary in shape and size, there is no one size to a sinkhole. Many sinkholes often fill up with water making a pond. With big sinkholes you often can’t see the bottom of them so it looks like an endless pit in the ground.

Sinkholes are very common around the world but they usually do no harm to humans and never draw too much attention, but there are some that have happened that has caused a lot of attention. Such as a sinkhole that has sunk eight cars in a Corvette car museum, very expensive and one of a kind cars, costing thousands of dollars in repairs and to fill up or cover the holes. There are hundreds of sinkholes that happen around the world causing homes, cars and other buildings to get damaged or destroyed.

With sinkholes people have spent thousands on repairing damage done and to fill up sinkholes or cover them. According to The Atlantic, Florida has had more sinkholes than any other state in the U.S. and studies have also shown that sinkholes are not super frequent but they are affecting more people, but NASA is trying to help by developing a remote sensor that can help detect the formation of sinkholes.
