Eroded coastlines typically form where sediment input is limited by cliffs, rock outcrop, or mountains abutting the beach environment. Weathering happens when natural events, like wind or rain, break up pieces of rock. beach, dune, barrier flat, high marsh, low marsh. 2. In this and similar cases like Cadiz, while the strip of beach material connected to the island may be technically called a tombolo because it links the island to the land, it is better thought of in terms of its formation as a spit, because the sand or shingle ridge is parallel rather than at right angles to the coast. 3.
