Basic objective of this lecture is to present on Coastal Landforms. It created by erosion include headlands, bays and cliffs. Landforms created by deposition include spits, salt marshes and beaches. At Coastal Landforms water becomes shallow, wave height increases because wave length decreases. Waves become steeper, then collapse (breakers). There are four key types of erosion: Abrasion; Hydraulic action; Attrition and Corrosion (also known as solution).
