Description
Sea arch. Sea arch projecting from a cliff into the sea. Sea arches are formed when a land promontory is composed of rock that varies in hardness. The softer sections of rock are eroded by the sea to a greater extent. Initially, caves form on either side of the promontory and gradually grow deeper until they join to form an arch. A sea arch will continue to be eroded by waves, growing wider until it collapses. When this happens a stack remains, as seen at left. This sea arch is the Green Bridge of Wales in Pembrokeshire, Wales.
