An explanation of the formation of the cove can be found on the right. However, structure is not the only factor influencing the indentation of Swanage Bay, since Swanage bay faces east, and is sheltered from the prevailing south westerly wind and highest energy waves. On discordant coastlines, differential erosion may occur, where bands of hard and soft rock outcrop at right angles to the sea. Then when the wave retreats, the compressed air expands again. The headlands are formed by the hard rocks such as limestone and chalk while the bays are formed as a result of the sweeping away of the soft rocks like clay and sand. Specifically looking at the differences between concordant and discordant coastlines. Deformation is the degree of tilting of folding ofrock. As mentioned earlier, discordant coastlines form headlands and bays; on the other hand, concordant coastlines form coves.

Waves can be gentle and infrequent or more significant, more frequent, and more powerful. The Bay is also a product of sea level rise, since river erosion cut a low-relief river valley into Carboniferous Limestone, allowing the sea to flood inland and creating a ria at the start of the Holocene. This is because access to the coast offers the opportunity for harvesting marine resources, especially fish, as well as the ability to conduct international trade via the sea.

Straight coastline now formed by a concordant band of constant chalk. The high degree of indentation of Bantry Bay is not solely influenced by the relative resistance of rock types, but also the orientation of strata SW-NE means that they directly face high energy Atlantic waves driven by the prevailing SW wind. Additionally, hotter temperatures enable extreme weather events like hurricanes to occur more frequently. Concordant. Concordant coastlines tend to have fewer bays . discordant coastline diagram.
