WebCoastal erosion may be caused by hydraulicaction, abrasion, impact and corrosionby wind and water, and other forces, natural or unnatural. [3] On non-rocky coasts, coastal erosion results in rock formations in areas where the coastline contains rock layers or fracture zones with varying resistance to erosion. WebThe geology and lithology will affect the rates of erosion and the speed at which the coastline recedes. Weathering and mass movement processes will also affect the rate of erosion.
