Explain the roles of flows of energy in the formation of a tombolo Shallow water, As waves near an island, they are slowed by the shallow water surrounding it. A single tombolo may connect a tied island to the mainland, as at Marblehead, Mass. 7. Cuspate Forelands Cuspate forelands are low lying triangular shaped headlands, extending our from a shoreline, formed from deposited sediment. They start to form where there is a change in the direction of the coastline. It is located on the northern side of the North Island, between the Tasman Sea and the Pacific Ocean. Each landform is a result of the action of certain geomorphic processes (endogenic and exogenic) and agents (rainfall, wind, glacier, waves). Strong waves carry large quantities of load over a long distance while weak waves carry small quantities of load over a short distance.

A tombolo, from the Italian tombolo, meaning 'pillow' or 'cushion' , and sometimes translated as ayre, is a deposition landform in which an island is attached to the mainland by a narrow piece of land such as a spit or bar. Beaches are made up from eroded material that has been transported from elsewhere and then deposited by the sea. Capes are formed when waves deposit sand into shallow water. 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). how is a tombolo formed geography - iccleveland.org Sand Dunes This prevents wind and waves from washing away the finer sediment on top of the bar.
