This means that these waves transport beach material back into the sea, lowering the height of a beach. Headlands and bays Cliffs along the coastline do not erode at the same pace. Along the coastline of Dorset, there are concordant and discordant coastlines. The outer hard provides a protective barrier to erosion of the softer rocks further inland. These coves are formed by waves breaking through an outer layer of hard rock, such as limestone, and then, over time, the waves sweep away the soft rock further inland, like sand and clay, creating a cove. Hydraulic action, attrition, abrasion, and corrosion. The bands of soft rock, such as sand . Wave cut platforms as illustrated in the diagram and shown in the photograph are remnants of the previous cliff line. It has a variety of other micro-features and a unique geology. A coastline with the same type of rock along its length; fewer bays and headlands . (For example the south or the Dorset coast) . This differential erosion creates headlands and bays along discordant coastlines. This continual process can weaken the joints and cracks in the cliff, causing pieces of rock to break off. This is called a discordant coastline. When the auto-complete results are available, use the up and down arrows to review and Enter to select. However, when the hard rocks punctured by either faults or ridges, inland soft rocks yield to erosion. Shingle ridge reconnected island of Portland Bill to land (a tombolo). For example, this could be a joint in chalk. As mentioned earlier, discordant coastlines form headlands and bays; on the other hand, concordant coastlines form coves.

The Isle of Purbeck, in Dorset, is an example of where a concordant and discordant coastline exist very close to one another. As the wave approaches the coast, it gains height and drops onto a steep beach. Sea level rise at the end of the Devensian Glacial overtopped the low points of the anticlines and the sea flooded synclines. They are also called spilling or surging waves.
