What are some examples of sea arches?

Sea arches are natural rock formations created by erosion. Notable examples include the famous London Arch in Australia, which was once a complete bridge before part of it collapsed, and the natural rock arch at the iconic Bow Bridge in Utah's Arches National Park. Other examples include the Durdle Door in England and the Rock Arch of Tóquio in Brazil. These structures are often found in coastal areas where waves continuously erode weaker rock layers.
