Choose the most likely scenario for how this rock formed. You can infer the environmental conditions where the rock formed from the characteristics of the clasts. For example, in places where sediments are affected by high-energy waves or wind, clasts will be weathered to a similar size and thus will be well sorted. In places with quiet, calm water, small clasts like mud are most likely to accumulate in thin layers. A.) Sediments were pounded by waves along a coast before they were covered by other sediments and cemented together. B.) Rocks eroded from mountains were deposited over a short time in a dry environment, where they were buried by other sediments and cemented into rock. C.) Sediments blown by wind accumulated in dunes over time and were gradually buried and cemented together. D.) Sediment from the bottom of a calm lake was laid down gradually and cemented into rock.
