A sinkhole, also known as a cenote, sink, sink-hole, swallet, swallow hole, or doline (the different terms for sinkholes are often used interchangeably), is a depression or hole in the ground caused by some form of collapse of the surface layer.Most are caused by karst processes – the chemical dissolution of carbonate rocks or suffosion processes. ...


Sinkhole definition is - a hollow place or depression in which drainage collects. How to use sinkhole in a sentence. a hollow place or depression in which drainage collects; a hollow in a limestone region that communicates with a cavern or passage; sink… See the full definition.


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.” These are ...


Sinkhole definition, a hole formed in soluble rock by the action of water, serving to conduct surface water to an underground passage. See more.


Like dissolution sinkholes, cover-subsidence sinkholes happen slowly. The most dangerous type of sinkhole is a cover-collapse sinkhole. In these cases, the bedrock is covered by a layer of clay.


Define sinkhole. sinkhole synonyms, sinkhole pronunciation, sinkhole translation, English dictionary definition of sinkhole. n. A natural depression formed by the undermining or sudden collapse of the land surface, often as a result of groundwater enlarging cavities in underlying...


A botnet sinkhole is a target machine used by researchers to gather information about a particular botnet. Sinkholing is the redirection of traffic from its original destination to one specified by the sinkhole owners. The altered destination is known as the sinkhole. (The name is a reference to a physical sinkhole, into which items apparently disappear.)


Sinkhole: Sinkhole, topographic depression formed when underlying limestone bedrock is dissolved by groundwater. It is considered the most-fundamental structure of karst topography. Sinkholes vary greatly in area and depth and may be very large. There are two main varieties, one caused by the collapse of the


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. Slowly, as the limestone dissolves and is carried away, the joints ...


Sinkholes can also form when natural water-drainage patterns are changed and new water-diversion systems are developed. Some sinkholes form when the land surface is changed, such as when industrial and runoff-storage ponds are created. The substantial weight of the new material can trigger an underground collapse of supporting material, thus ...
