WebRefraction of waves causes it to spread across the coastline and enter coves or bays. This energy is then concentrated on the headlands where it causes erosion to occur. A beach can form because the wave energy is dispersed through bays, which reduces wave power and favors silt deposition. Deposition happens when approaching wave crests closely … 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.

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. WebThe Atlantic coast may at one time been tectonically active, but is no longer. Critical thinking questions. 1)Explain how wave refraction affects erosion and sediment deposition along an irregular coastline.

WebWave refraction and currents cause the wave’s energy to disperse, which leads to deposition forming on the seabed. Over time, the amount of sediment deposited is exposed, extending the beach into the sea as a spit. Three factors determine the length of a spit: secondary currents causing erosion, the flow of a river, and wave action.
