Natural arches are geological formations that consist of a rock or land structure with a hole or opening that allows light to pass through. They are typically formed through processes of erosion, where wind, water, and other natural forces wear away the surrounding material, leaving an arched structure that spans a crevice or a gap. Natural arches can be found in many types of rock formations, including sandstone, limestone, and granite, and they can vary significantly in size and shape.
