Sea landforms Coastal processes are the most dynamic and hence most destructive. . At one place, there can be erosion in one season and deposition in another o Most of the changes along the coasts are accomplished by waves. o Erosional features are dominant in High rocky coasts, Erosional features are dominant in High rocky coasts, depositional features are dominant in low sedimentary coasts . West coast of India- erosional features; east coast of depositional features
Erosional features Sea Cliffs: Steep rocky coast rising almost vertically along the coast Look like overhanging portions
Erosional features Wave cut platforrock cut fat surface in front of ciffs Wave cut platforms: rock cut flat surface in front of cliffs Origin is related to cliff recession covered by rock debris derived from the sea cliff behind Sea caves: Formed along the coast due to gradual erosion of weak and strongly jointed rock. # Formed frequently in carbonate rocks - Stacks: remnants of rock standing isolated as small islands just off the shore Resistant masses of rock, originally part a cliff or hill - s o
Depositional features Beaches: Beaches are characteristic of shorelines that are dominated by deposition Most of the sediment making up the beaches comes from land carried by the rivers or from wave erosion. . Sandbars: Mounds of sand formed by sedimentation through sea wave parallel to the shoreline Larger form of bars are called barriers
Depositional landfornm Depositional landforms - Spits: sandbars in which one end is connected to the land and the other end is projected into the sea Tombolo: A sand bar connecting two headland or one headland and an island.
