Coastal and Oceanic Landform ( 53. Wave Cut Platform )

                                                                                                                  Back to Coastal and Oceanic Landform

• A wave-cut platform called as;

                                                       Coastal benches
                                                       Wave-cut benches
                                                       Shore platform

• It  is the narrow flat area.

• Found at;

                        The base of a sea cliff.
                        Along the shoreline of a lake, bay, or sea.

• That created by the wave action.

• Wave-cut platforms are low tide.

• Landward side is covered by sand.

• It undercutting between high & low water marks.

• It result of corrosion and hydraulic power.

• Then creating a wave-cut notch.

• This notch  enlarges into a cave.

• The base forms as attrition.

• Cliff material  washed into the sea.

• Raised and abandoned platforms found behind modern beaches.

• Evidence of higher sea levels.

• Where the coastline changing seismic action.

• The platforms showing earlier sea levels.

• Those indicating the uplift caused by various earthquakes.

• Shore platforms comparable river & lake platforms.

• They are erosional features develop when removal of saprock.

• Other debris by waves & currents leaves behind a bedrock surface.
