Headlands are formed as the result of coastal erosion and the tremendous battering power of the sea and its waves coupled with ice, rain, and wind. Parts of the headland that jut out into the water slowly get eroded over time by the mechanical energy of winds and waves. Transportation and deposition processes produce distinctive coastal landforms (beaches, recurved and double spits, offshore bars, barrier beaches and bars, tombolos and cuspate forelands), which can be stabilised by plant succession.

Headland cliffs are cut back by wave erosion and the bays are filled with sand deposits until the coastline becomes straight. The ecological balance of these landforms is crucial for retaining the equilibrium both in terrestrial and marine life. A headland, also known as a head, is a coastal landform, a point of land usually high and often with a sheer drop, that extends into a body of water.
