Over time, deposition will occur in the bays and so forming beaches. In lower-energy pocket beaches, sediment transport is not able to carry sediment downshore except during increased wave, wind, and storm activity. Bays are made up of soft rocks while headlands are made up of hard rocks. Over time, erosion can cause cliff collapse therefore the coastline needs to be managed. Then the balance changed, and wind and water went to work to create the geological wonderland we see today. . For a few more million years, the land built up faster than it was eroded away.

Parts of the headland that jut out into the water slowly get eroded over time by the mechanical energy of winds and waves. For each landform you need to understand how processes of weathering (freeze thaw, hydration, biological, salt crystallisation), mass movement (slumping, slides, rock falls) and erosion (Hydraulic Power, Corrasion, Corrosion) contributes to the formation. Bands of soft rock such as clay and sand are weaker therefore they can be eroded quickly. Headlands are characterized by .
