Geological sinkhole.
Most sinkholes occur in places where water can dissolve the rock below the surface, for example where the bedrock is limestone, salt, or gypsum.

Land subsidence is a gradual settling or sudden sinking of the Earth's surface owing to subsurface movement of earth materials. The principal causes of land subsidence are aquifer-system compaction, drainage of organic soils, underground mining, hydrocompaction, natural compaction, sinkholes, and thawing permafrost.In the preliminary report, the Bureau of Economic Geology, a research unit at the University of Texas, said the new sinkhole has a diameter of about 230 feet (70 m) and is about 30 feet (9 m) deep.

Once sinkholes develop, they can cause significant damage to property, pose safety threats, and are typically costly to repair.
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.

An extended drought, punctuated by occasional heavy rains, commonly triggers increased sinkhole activity. A collapse sinkhole
Sinkholes are holes or depressions that form when water washes sediment down into cracks and voids in karst bedrock. Sinkholes form from the bottom up as the sediment immediately above the bedrock is the first to be washed into the voids. The land above a sinkhole often appears normal until a critical amount below has been washed away.Geologic maps and other geologic data can provide information on past land-use in historic mining areas of the State.

Although sinkholes are common in Florida, Devil’s Millhopper is unique because it is one of the few places in Florida where more than 100 feet of geologic strata (rock layers) are exposed. The park is also unique because it is an important and beautiful example of how ecosystems (flora and fauna) develop in response to geological features. Sinkholes are a geological hazard that place peoples property and even lives at risk. Vulnerability of an area to sinkhole formation is dependent upon both natural (geologic, hydrologic, and meteorologic) and human (water pumping, terraforming, ground loading) factors. As Floridas population continues to surge and development encroaches on ...Geological maps of the area will show known sinkholes. Old aerial photographs regularly reveal sinkholes that are easy to spot if you know what to look for. Therefore, sinkhole formation is not entirely unpredictable if you consider the rock type and take a peek into historical evidence.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.

Collapse sinkholes are found in groundwater recharge zones throughout the world. They cause substantial loss of property each year, and occasional fatalities. In such settings, the formation of these features occurs through the downward migration of regolith into karst voids. The presence of a void in the bedrock, and sufficient seepage pressure …Both of these geological features are sinkholes, formations that are much more than holes in the ground. 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].Those unexpected sinkholes are mostly the ones that open up and consume cars, roads and homes.

Sinkholes can vary from a few feet to hundreds of acres and from less than 1 to more than 100 feet deep. Article Vocabulary 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. These cracks are called joints.
