WebAs the waves erode the coastline, the soft rock will be eroded quicker. This results in the areas of softer rock to retreat, forming bays, whilst the hard rock is eroded slower so will form headlands. Over time, deposition will occur in the bays and so forming beaches.
WebLong narrow bays have formed where the weaker rock has been eroded. These were old river valleys which were drowned by rising sea levels after the last Ice Age. Hard resistant rocks remain as islands off the coast (Clear Island). Headlands are eroded more than bays which leads to the smoothing of the coastline overtime. WebAs a wave breaks, water rushes up the beach (swash) and is then carried back down the beach by gravity (backwash). The amount of percolation of the swash depends on the porosity of the beach material. When waves approach a coast with headlands and bays, the waves are refracted.

Soft rock bands, such as clay and sand, are weaker, so they can be quickly eroded. Bays are formed as a result of this process.
