It causes physical weathering of the rocks in warm regions and fragments in the rock in the cold areas when water freezes inside the holes of the rock and expand to create a crack in it and thereby yield sediments. During these weathering events, the sediment is washed away by the rain or wave action. These coasts are composed of different types of rocks, namely igneous, sedimentary, or metamorphic and are filled with complex tectonic landforms like folds, faults, and igneous intrusions and extrusions.
