The diagrams illustrate the process of headland erosion, depicting four stages from the erosion of rock to the formation of a stump. This erosion occurs at a headland located near a beach.
Initially, the headland stands like a strong wall; however, its lower part begins to weaken and erode. This stage creates a hollow in the headland, which eventually transforms into an arch, similar to Durdle Door in Dorset. As the waves continuously batter the cave, they break the roof, leaving behind a stack that is separated from its original land.
After the stack is formed and separated, the headland continues to retreat, moving closer to the stack. Nevertheless, this process results in the creation of a stump in the ocean. This cycle may repeat due to the intense pressure exerted by the ocean’s waves.
In conclusion, the headland is likely to collapse when exposed to strong waves. Additionally, the eroded headland can give rise to a stack and a stump in the ocean, which are located in different areas from the original land.
