A river delta is a landform that forms from the deposition of sediment carried by a river as the flow leaves its mouth and enters slower-moving or standing water. Every river on the surface of the earth flows from its source to its mouth under the natural force of gravity. The battle between the river’s flow and the amount of sediments it carries, and the strength of the tidal waves of the body of water, determines the delta’s shape. A delta bond occurs when all four lobes of a d orbitals interact with one another. The cuspate deltas are formed where sediments are deposited onto a straight shoreline with strong waves. The waves push the sediments to spread outwardly creating the tooth-like shape.
