   What is a solution sinkhole?

   • Solution sinkholes are most commonly seen in areas with a very thin soil cover on the surface, exposing the bedrock below to continual erosion by water. As the water percolates through the bedrock, it carries away small parts of the rock with it. As the bedrock erodes, particles collect in the spaces it leaves.

   How do dissolution sinkholes form?

   • Dissolution sinkholes start to form when limestone or dolomite is very close to the soil surface, usually covered by thin layer of soil and permeable sand which washes away or is eroded. Rainwater then progressively dissolves the exposed limestone and as a result, a bowl-shaped depression gradually forms.

   What are the different types of sinkholes?

   • There are several different types of sinkhole (also known as dolines) caused by different processes, including dissolution, collapse and erosion. 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.

   What is a sinkhole?

   • Wikipedia defines Sinkhole as, “ A sinkhole, also known as a cenote, sink, sink-hole, shakehole, 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.

   How do sinkholes form?

   • BGS © UKRI. Sinkholes can also form as a result of both dissolution and subsequent collapse. Where a thin covering of loose, superficial material (such as sand, clay or soil) covers the soluble rocks beneath, the soil can be washed into solutionally widened fissures or cavities below.

   How does water affect sinkholes?

   • Water is responsible for about 90% of all sinkholes, and this is how: If the rocks below the surface are made of materials that dissolve in water, like limestone and gypsum, the water dissolves these minerals with time, opening spaces within the rock. This process is known as weathering and results in sinkholes.

   Dec 18, 2017 · As the name describes, dissolution – the process in which a solid substance moves into a solvent to make a solution – is the driving factor for this type of sinkhole. Dissolution sinkholes start to form when limestone or dolomite is very close to the soil surface, usually covered by thin layer of soil and permeable sand which washes away or ...

   Mar 15, 2023 · A sinkhole is a depression or cavity caused by collapse of the surface layer due to loss of support from below. If the surface layers are sandy, they will slump into the void below and the surface depression will widen gradually over time.

   1. Dissolution Sinkhole. Also known as solution sinkholes, this types of sinkholes occur where there is little soil or vegetation over the soluble bedrock. Rain and runoff water gradually percolate through crevices in the rock, dissolving it. Consequently, a depression slowly forms.

   These are called solution sinkholes. These rocks dissolve when attacked by rainfall or groundwater that is acidic. Solution sinkholes have sides that vary from gentle slopes to almost vertical, while their shapes include saucer-like hollows, cones, cylindrical potholes and shafts.
