This is a natural rock arch taken as a photo from Italy. At first glance, I deem this as certainly an image of nature with no artificiality whatsoever. Nonetheless, have you ever asked yourself how an arch such as this was created in the first place? Water erodes rocks, sand, and sendiment over time, eating away these materials together with water pressure to create shapes such as these but because of many human projects leading up to acid rain and other negative effects, the rate of erosion has been directly influenced causing these arches to fastly disappear. So the question is, has this particular arch been naturally created or artificially?
