Waves and Currents
Coastal processes refer to those dynamic and also most destructive. Changes that occur on the coast are because of the waves. The constant impact of the breaking of the waves would affect the coasts and the tsunami waves may cause far-reaching changes in a short span of time. The coastal landforms also depend on:
- Configuration of land as well as seafloor
- Whether the coast is advancing or retreating landward
Erosional Landforms
Erosional landforms are of the following types for waves and currents:
- Wave-cut cliffs
- Terraces
Depositional Landforms
Depositional landforms are of the following types for waves and currents:
- Beach
- Bars
- Barrier Bar
- Spits
- Lagoon
- Tombolo
Evolution of Landforms
Evolution of Landforms: The evolution of landforms refers to the different processes of transformation of one landform to the next, or the transformations of individual landforms once they are formulated. A landform goes through various stages of development- which are youth, maturity, and old age.
Erosion and deposition are the two important parts of the evolution of landforms and the geomorphic processes are unavoidable. and usually takes place slowly and over a long duration. The evolution depends on the geomorphic agents which include groundwater, glaciers, waves, and winds. Both the processes of erosion and deposition change the surface of the earth.
