WebA wave-cut notch (small scale landform) is formed by erosional processes such as abrasion. and hydraulic action, this is a dent in the cliff usually at the level of high tide. WebSand dunes are created when wind deposits sand on top of each other until a small mound starts to form. Once that first mound forms, sand piles up on the windward side more and more until the edge of the dune collapses under its own weight. The collapse begins when the angle of the dune becomes too large to support the weight.
