A sea arch is a natural arch or bridge made of stone that is created when water erodes the bottom of a rock, leaving only the top behind. They usually form where cliffs meet the sea.
The Blue Window is a sea arch located in Malta.
Natural arches are created through the process of erosion by soil, wind, or water, or some combination of these methods. They are usually formed by the meeting of two types of rocks, the harder substance is found in the upper part of the arch, which forms the bridge. When the bottom rock is a softer type of stone, it disintegrates more quickly, leaving an arch.
The sea arch of Australia’s London Bridge collapsed in 1990.
A sea arch is created when the natural erosive forces of water cut through a piece of rock and leave behind an arch. After all, water is one of the most powerful forces on the planet. It has the power to destroy cities, but it also has the power to make impressive sculptures on earth, like the Grand Canyon.
Beautiful sea arches exist all over the world. A particularly well-known one called “London Bridge” was located near Victoria, Australia, but collapsed into the water in 1990. Others include Durdle Door and Stair Hole on the coast of southern England.
These arches are often formed from ancient caves. In many cases, a limestone cave riddled with holes begins to collapse, leaving behind what was once the mouth of the cave. This previous entry then becomes an arch.
Durdle Gate is one of the sea arches in the south of England.
As every sea arch is the result of erosion, many of them will eventually collapse, like London Bridge in Australia. Depending on the age and structure of the arch, it can appear strong and durable, or fragile, ready to collapse on itself. However, when one becomes rubble at the edge of the ocean, another is likely to take its place as a cave collapses in on itself or a splinter or weak rock finally gives way to allow wind and water to pass through. strongest arch above.
