Quizplus · Accepted Answer

The rounded, smooth shape and sorting of the rocks suggest that they have been transported a long distance by waves, which would have eroded and reshaped them. The lack of any fine-grained sediment, such as sand or silt, also suggests that the environment was highly energetic and capable of carrying and sorting larger particles. The absence of any visible wind-related features or evidence of lacustrine (lake) deposition further supports the idea that the rocks were moved by the action of waves in a marine environment.
