Flowing water is the dominant natural force causing erosion and deposition on Earth. The faster the water moves, the higher the energy in a physical setting. As flowing water increases in speed, the more it may become turbulent, increasing its ability to lift and move particles.
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.

A depositional environment is a particular location on the earth surface (e.g., river channel, tidal inlet, submarine fan, reef) where a limited range of physical, chemical, and biological processes take place, resulting in the generation of a limited range of sedimentary deposits. The huge 1964 Alaskan earthquake was caused by. the fault suddenly uplifts or downdrops the seafloor. sudden movement on a fault can cause a tsunami when. causing a large mass of rock to catastrophically displace the water. Landslides and earthquakes can cause a tsunami by. a strike-slip fault on land.Gypsum is a common primary and secondary mineral of arid and semi-arid region soils. Gypsum is by far the dominant sulfate mineral in soils. A saturated gypsum solution at 25C contains ~15 mM CaSO 4, or 2.63 g/L.
