WebThe deposition of sediment forms a spit but its shape changes as a result of wave refraction. Refraction around the end of a spit curves it into a “hook” forming a recurved spit. As the area behind a spit is sheltered from waves and the wind, it provides the perfect environment for salt marshes to develop. WebThe shore is an area that extends between the lowest tide levels and highest point that storm waves affect. Shorelines are the place where the sea meets the land. The coast is the area that extends inland from the shore as far as ocean features are found. Coastlines are the places that mark the coast’s seaward edge.

$Refraction of waves - Reflection and refraction - BBC Bitesize$

WebWave refraction refers to what happens to waves when they approach an uneven coastline. Very few coastlines are perfectly straight, and few sea beds have uniform height and shape. This is known as the varying Geomorphology of our coastline and it will affect the waves travelling above it and towards it in differing ways. WebWave refraction and diffraction cause converging wave fronts on headlands and diverging wave fronts in bays. This phenomenon concentrates wave energy on headlands and diffuses wave energy in bays.

Critical thinking questions. 1)Explain how wave refraction affects erosion and sediment deposition along an irregular coastline. As a wave is refracted moving towards an irregular coastline (protruding cliffs) they converge toward the headlands.

WebCoastal processes Processes called erosion, mass movement and weathering break down and remove material from the coast. Many factors affect the rates of coastal erosion and … WebErosion - waves can erode the coastline in a similar way to the water in rivers. This usually occurs when the sea takes lots of energy from the power of destructive waves. …

WebWave Refraction Swell can be generated anywhere in the ocean and therefore can arrive at a beach from almost any direction. But if you have ever stood at the shore you have probably noticed that the waves usually approach the shore somewhat parallel to the coast. This is due to wave refraction. WebMar 1, 2024 · How does wave refraction affect longshore drift and beach erosion? As the wave approaches the shore the wave is bent or refracted as the leading edge slows in the shallows. This refraction forms a current that moves parallel to the coastline known as longshore drift or longshore current.
