The process of longshore drift occurs and this moves material along the coastline. What are spits and Beaches and spits are examples of depositional landforms. There may be 3 locations of bars in the bays viz. A small piece of land, such as an island, or a beached shipwreck can change the way that waves move, leading to different deposition of sediments. As the name suggests, The Spit extends into the seaway and is the gateway between the Gold Coast Broadwater and the open ocean.

Spits are formed where the prevailing wind blows at an angle to the coastline, resulting in longshore drift. A tombolo, from the Italian tombolo , meaning 'pillow' or 'cushion', and sometimes translated incorrectly as ayre (an ayre is a shingle beach of any kind), is a deposition landform by which an island becomes attached to the mainland by a narrow piece of land such as a spit or bar.

A tombolo is a sediment deposit at the coast formed by wave refraction and diffraction at the edges of an obstacle (natural or artificial) originally detached from the mainland. The island is then referred to as a linked island once it has been joined.Due to sand accretion in the lee of the island, where wave energy and longshore drift are reduced and hence sand deposition occurs, the shoreline creeps toward the island (or detached breakwater). csee necta questions Beaches. On deposition-dominant coasts, the coastal sediments are still being eroded from some areas and deposited in others. Activate your 30 day free trialto unlock unlimited reading.
