A tombolo is formed when a spit connects the mainland coast to an island. The process of longshore drift occurs and this moves material along the coastline. The associated biological processes are enhanced where upwelling currents bring chemical nutrients from deeper water (but not so deep that the water is cooler than about 25C) (Figure 17.24). Sea level rise may also contribute to accretion, as material is pushed up with rising sea levels. Transportation by longshore drift is favored where the coast is aligned obliquely to the direction of breaking waves while on transversely aligned coast swash moves materials back and forth along the same line. Answer: Sandspits and Tombolos both are depositional landforms created by waves in coastal areas.
