Cliff erosion is the process by which cliffs are worn away by natural forces such as water, wind, and ice. Over time, waves crashing against the base of a cliff can remove material, while rainwater can seep into cracks, causing the rock to weaken and break apart. This gradual wearing down can lead to the collapse of large sections of the cliff. Factors like weather, geology, and human activity can influence the rate of cliff erosion. For example, heavy rainfall can increase erosion, while construction near the cliff edge may destabilize the soil. Understanding cliff erosion is important for managing coastal areas and protecting habitats.
