- Geological Structures
- concordant coastlines - alternating bands of hard and soft rock parallel to the sea
- lead to the formation of Dalmatian coasts - made up of offshore islands running parallel to the coastline
- Lulworth Cove - SW Dorset where more resistant rock protects the less resistant
- lead to the formation of Dalmatian coasts - made up of offshore islands running parallel to the coastline
- discordant coastlines - alternating bands of hard and soft rock 90 degrees to the sea
- erosional landforms are more common as erosion happens at different rates
- Dorset - Portland limestone erodes slower than the Greensands - headlands and bays
- headlands and bays - less resistant rock and the exposed resistant rocks cause a change in the shape of the coastline - wave refraction
- wave refraction causes increase in erosion on the headlands - erosional landforms e.g caves etc
- coastal morphology - shape of a beach and its features including type of sediments at different locations on the beach
- joints and faults
- sedimentary rocks - susceptible to erosion and weathering - exert forces on the weakness in the rock
- dip
- angle of the rock layer
- towards the sea create gentler profiles but are vulnerable to mass movement
- towards land create steeper cliff profiles are more vulnerable to erosional processes e.g AASHA
- geology - joints, dip, faulting, folding
- concordant coastlines - alternating bands of hard and soft rock parallel to the sea
