Sea Arch is a natural opening in the shape of a cliff, it is developed when the waves collide with the rock. Water at the bottom of the ocean is incredibly hot. This refraction of waves concentrates their energy in specific locations along the headland, causing particularly rapid erosion if weakness such as faults and fractures are present in the rocks.
