Since the start of civilization, humans have settled along rivers and subsequent delta formed by them. The outcome is a unique series of layers called topsets, foresets, and bottomsets. The shape of the delta is like a claw. For a delta to form, the rate of deposition must exceed the rate of sediment removal. The foresests are subsequently covered by a new set of topsets as sediment accumulates, and the cycle continues. Should Geologist Students Consider Taking Up Geosciences At The University Of Arizona?
