Geological research and fluid-mechanical studies confirm that round holes, or potholes, in stones and bedrock are formed through specific erosional processes such as fluvial abrasion, cavitation, and swirling water currents.
The claim posits that round holes in stones are formed by specific geological and erosional processes. Papers [7], [8], and [9] directly investigate natural potholes in riverbeds, demonstrating that they are created by fluvial erosion, abrasion, cavitation, and fluid-driven vortices. The evidence consistently supports the geological origin of these features, yielding a verdict of SUPPORTED.
