the water hits the rock and wears it down

Erosion can wear away cliffs through processes like weathering, where water and wind break down rocks over time, and by the force of waves crashing against the base of the cliff, causing it to gradually crumble and collapse. Additionally, the action of gravity can cause rocks and debris to fall from the cliff face, further contributing to its erosion.
Water erosion, caused by the flow of water carrying away soil and sediment. Wind erosion, when wind blows soil particles away from their original location. Glacial erosion, as glaciers move over the land, scraping and carrying away rocks and sediment. Coastal erosion, where waves and tides wear away coastlines, cliffs, and beaches.
Happisburgh is at risk of erosion due to its location on the North Sea coast of England, where coastal processes such as wave action and storm surges constantly wear away the cliffs. Additionally, the cliffs at Happisburgh are composed of soft sedimentary rock that is susceptible to erosion. Climate change and rising sea levels further exacerbate the erosion in this area.
Waves cause erosion by carrying and moving sediments along the coastline. The force of the waves can gradually break down and wear away rocks and cliffs, leading to erosion of the coastline over time.
The primary agent of erosion that causes ocean cliffs to erode is wave action. The force of waves, along with the corrosive effects of saltwater, gradually wears away the rock and soil of the cliffs over time. This process is known as coastal erosion.
Crashing waves can cause erosion because the force and energy of the waves can wear down coastal rocks and cliffs over time. The constant impact of the waves can break apart rocks and carry away sediments, leading to the gradual erosion of the coastline.
