Ice eggs form in northern Finland due to strong wind and cold weather, giving the shores a dragon egg-like appearance.

The phenomenon of ice eggs forming in northern Finland is well-documented with moderate-level evidence from reliable sources such as BBC and ExplorersWeb. This occurs under specific weather conditions, such as strong winds and cold temperatures, which cause small pieces of ice to grow by rolling, explaining how the ice eggs form. No evidence supports the claim about ice rolling related to a process involving these natural ice formations; available evidence discusses cosmetic or industrial processes unrelated to natural ice formation phenomena. Therefore, the claim about ice eggs is verified with supporting evidence, while the claim about ice rolling remains unverified. The opinion-based description of Finnish shores resembling dragon eggs is not fact-checkable.
