Where do sinkholes occur?
There are several different types of sinkhole (also known as dolines) caused by different processes, including dissolution, collapse and erosion. Dissolution. Some sinkholes result from the surface dissolution of soluble rock. For example, limestone rocks dissolve when attacked by rainfall or groundwater that is acidic. Soluble rocks in the UK.
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...

Sinkholes are usually created by the natural erosion or gradual removal of slightly soluble carbonate bedrock e.g. limestone or gypsum, by acidic rain percolating through and dissolving the bedrock or by the inward collapse of a cave roof.
Sinkholes mainly occur in what is known as ‘karst terrain’; areas of land where soluble bedrock (such as limestone or gypsum) can be dissolved by water. With cover-subsidence sinkholes the...
Feb 8, 2017 · The cause of a sinkhole is fairly straightforward. It's the stuff immediately below the surface shifting to somewhere else. A sinkhole can range anywhere between a slight depression in the ground right up to an enormous hole reaching down half a kilometre. The world's deepest sinkhole is in Chongquig, China, reaching down 662 metres.
Dec 18, 2014 · But what exactly is a sinkhole and how and why do they open up? Sinkholes can take thousands of years to form and usually happen when rock underneath the ground is dissolved by acid rain.
Most sinkholes are caused by karst processes – the chemical dissolution of carbonate rocks, collapse or suffosion processes. [1][5] Sinkholes are usually circular and vary in size from tens to hundreds of meters both in diameter and depth, and vary in form from soil-lined bowls to bedrock-edged chasms.
