What is the difference between a cuspate and arcuate delta?

In: Geography, Lakes and Rivers [Edit categories]

Answer:

A cuspate delta is formed when a river drops sediment onto a straight shoreline with strong waves. Waves force the sediment to spread outwards in both directions from the river's mouth, making a pointed tooth shaped with curved sides by regular opposing, gentle water movement; an arcuate delta is formed when a river meets the sea in a place where the waves, currents and tides are strong, and are found in areas where longshore drift keeps the seaward edge of the delta trimmed and relatively smooth.
