Ps
thank u so much sir...
we are grateful to the entire team of unacademy for giving us such good quidence....................spectacular sir
the videos are good and helpful but we need the course to be more elaborate with more pictures and detail and once again thank you
Concepts are clearly explained with the help of pictures.Thank you sir! Just have one doubt- why the erosional landforms called temporary ??? Because they actually take number of years to form.
Thank you for coming up which such good explanations

  3. 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


  4. Erosional features Sea Cliffs: Steep rocky coast rising almost vertically along the coast Look like overhanging portions


  5. 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


  6. 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


  7. 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.
