Sedimentary rocks are structured randomly when deposition of sediment takes place out of air, wind, gravity, ice or flow of water handling particles in the form of suspension.
Explanation:
Weathering process belongs to sediments breakage into loose material, Erosion is sediments picking-up, Transportation is sediments movement, Deposition is the location where final deposition of sediment take place, Burial is formation of layers of collected sediment while Diagenesis is the process when sedimentary rocks result from the activity of sediments.
