Transitional.What does grain size indicate about a specimen’s environment and the energy of transport? Grain size is related to the energy of the depositional environments. The energy of transport can be by wind, water, glaciers, and gravity. For example, if the grains are the same size, the sediment was sorted during a long transportation.the depositional environment. Sediment deposited rapidly in areas of little current or wave action is usually poorly-sorted, because there is little chance for the removal of fine-sized grains. There is more opportunity for size sorting when sediment slowly accumulates in a high-energy environment.Facies and depositional environment of the Holocene evaporites in the Ras Shukeir area, Gulf of Suez, Egypt M.A.M.
