A sinkhole is a depression in the ground that has no natural external surface drainage. Basically, this means that when it rains, all of the water stays inside the sinkhole and typically drains into the subsurface. Sinkholes are most common in what geologists call, “karst terrain.”
A sinkhole is a depression or hole in the ground caused by some form of collapse of the surface layer. The term is sometimes used to refer to doline, enclosed depressions that are also known as shakeholes, and to openings where surface water enters into underground passages known as ponor, swallow hole or swallet.
Oct 19, 2023 · A sinkhole is a hole in the ground that forms when water dissolves surface rock. Often, this surface rock is limestone , which is easily eroded , or worn away, by the movement of water. In a landscape where limestone sits underneath the soil, water from rainfall collects in cracks in the stone.
Jun 9, 2018 · A sinkhole is an area of ground that has no natural external surface drainage--when it rains, the water stays inside the sinkhole and typically drains into the subsurface. Sinkholes can vary from a few feet to hundreds of acres and from less than 1 to more than 100 feet deep.

Apr 8, 2024 · A sinkhole is basically a hole which appears to suddenly open up in the ground. However, the process that leads to a sinkhole is not so sudden and may have been developing over a long period.
Sinkholes typically form when naturally acidic rainwater erodes underlying bedrock, creating damage beneath the surface. Their formation is most common in easily erodible karst terrains with...
Jan 9, 2016 · What is a sinkhole. They go by called many names (snake hole, swallow hole, or doline). They’re big, they appear seemingly out of nowhere, and they can “devour” houses in the blink of an eye.
Nov 2, 2023 · Though many are less than 100 feet (30 meters) deep, sinkholes can look like ponds, cover hundreds of miles or fit discreetly in your backyard [source: USGS]. In this article, we'll cover how sinkholes occur and what problems they cause. Contents.
Dec 14, 2020 · According to the U.S. Geological Survey, there are three common types of sinkholes: 1) dissolution, 2) cover-collapse, and 3) cover-subsidence. To understand how sinkholes work, let’s take a look at the cover-collapse formation type as an example.
