Such a cavity is formed in many types of rock and by many processes. The largest and most common caves are those formed by chemical reaction between circulating groundwater and bedrock composed of limestone or dolomite.
- Cracks are formed in the headland through the erosional processes of hydraulic action and abrasion.
- As the waves continue to grind away at the crack, it begins to open up to form a cave.
- The cave becomes larger and eventually breaks through the headland to form an arch.
- The base of the arch continually becomes wider through further erosion, until its roof becomes too heavy and collapses into the sea. This leaves a stack (an isolated column of rock).

Oct 17, 2024 · Processes of erosion have led to the formation of distinctive coastal features - we call these erosional landforms. Headlands jut out into the sea as they are made from resistant rock with erodes more slowly than the surrounding rocks. However, they are hit by destructive waves because of wave refraction to they are constantly being re-shaped be erosion. This creates landforms such as caves ...
Jun 27, 2023 · The Fingal's Cave in Scotland is an example of a littoral cave. Also known as a littoral cave, sea caves refer to those caves formed by the action of sea waves on fractures in the bedrock of sea cliffs along coastlines worldwide.
