What is a Sinkhole?

Spread the love

A sinkhole is a natural depression in the Earth’s surface. They are formed when water seeps into bedrock, causing it to dissolve. The ground sinks away and literally leaves a hole! They can be huge, enough to sink roads or houses or they can be small and just enough to cause a problem in your garden. These types of sinkholes generally aren’t too deep and often don’t cause any injuries. A sinkhole may look dramatic, but it is not dangerous unless it affects a nearby building or home.

The process of sinkhole formation is very simple. It occurs when rocks or dirt fall into the ground due to water drainage issues, resulting in a hole. Large sinkholes may show an underground stream at their bottom. They are usually found in areas where there is a lot of groundwater flowing, such as limestone, carbonate rock, salt beds, or rock fracking. If there is an underground pipe leak that weakens the subsoil or a mains water leak, a hole can appear in a lawn or paved area on a property.

Sinkholes vary in size. The bottom of a sinkhole is usually surrounded by soil or mud. They can be deep or shallow. In some cases, they can be completely submerged. However, sinkholes rarely happen overnight. According to a geology professor, a sinkhole can take years to form. This is because of the processes and conditions necessary to develop it.
