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. 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 … iphonese2续航 https://transformationsbyjan.com

This results in the areas of softer rock to retreat, forming bays, whilst the hard rock is eroded slower so will form headlands. Over time, deposition will occur in the bays and so forming beaches. People also asking: What is a phospholipid and what is its function? 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. orangeburg sc birth records
