Features of a bar Flashcards
When does a bar form from a spit
A bar forms when a spit grows to form a ridge that blocks off a bay creating a lagoon between the mainland and the bar. An example of a bar is in Slapton Sands in Devon
How may a bar alternatively form sea levels
A bar may start as a deposit out at sea that is driven onshore by rising sea levels. As sea levels stabilise it becomes a relict feature for example Chesil Beach in Dorset
What is a bar called if not connected to mainland
It is called a barrier island for example Scolt Head Island off the North of Norfolk coast
What is a tombolo
A tombolo is a spit or bar that joins the mainland to an island for example the Eastern end of Chesil Beach where it joins the Isle of Portland
What is cuspate foreland?
Cuspate foreland is a triangular-shaped projection from the shoreline made up of a series of ridges created by long shore drift from opposing directions.
A famous example is Dungeness in Kent
