How does longshore drift transport material
WebProcesses called erosion, mass movement and weathering break down and remove material from the coast. Many factors affect the rates of coastal erosion and the landforms created. WebMar 22, 2024 · As the wave breaks at the foot of the cliff, material is thrown at the cliff face and wears it away by chipping fragments off. Solution– this process occurs when weak carbonic acid in seawater dissolves rock at the coastline and breaks it down (particularly that containing calcium carbonate such as limestone and chalk).
