Headlands and bays form on discordant coastlines, where bands of rock of alternating resistance run perpendicular to the coast. Waves are refracted around the headlands, increasing erosion at seaward positions on the islands in the park. These caves are distinctive environments that are particularly suited for bryozoans, sponges, barnacles, tubeworms, and some species of shade-tolerant red algae. Tides play two types of role in the formation of landforms. Headlands and bays are formed when there are parallel sections of softer and harder rock perpendicular to the coast.

The altering rate of erosion of hard and soft rock is known as differential erosion. There is also erosion by wind, weathering, sub-aerial processes, and mass movement. Sandy beaches are usually found in shallow bays with fewer waves and shallow water. Through the deposition of sediment within the bay and the erosion of the headlands, coastlines eventually straighten out, then start the same process all over again.

Bands of soft rock such as clay and sand are weaker therefore they can be eroded quickly. Required fields are marked *. Cliffs are usually formed because of processes called erosion and weathering. When the sea attacks a section of the coast with alternating bands of hard and soft rock, headlands form. Certain landforms further reduce waves erosive power. Small landforms created by the waves and sediments from lakes are termed lakeshore landforms. The water contains sand and other materials that grind away at the rock until the cracks become a cave.
