Weathering and erosion are critical processes in the formation of sea arches and sea stacks. Weathering breaks down rocks along coastlines through physical, chemical, and biological processes, weakening the structure of cliffs and shorelines. As waves continuously crash against these weakened rocks, erosion occurs, removing debris and carving out caves. Over time, persistent erosion can lead to the collapse of sections of rock, leaving behind sea arches—freestanding arches of rock—and sea stacks, which are isolated pillars of rock standing offshore.
