Study Notes
Formation of a Tombolo
- A tombolo forms when a spit connects the mainland to an island, creating a landform that bridges both landmasses.
- Longshore drift is the process where sediment is moved along the coastline, playing a crucial role in the development of a tombolo.
- Swash occurs when waves, driven by the prevailing wind, transport sediment up the beach, contributing to the build-up of the spit.
- The returning backwash, influenced by gravity, drags sediment down the beach at right angles, affecting the overall sediment distribution.
- St Ninians tombolo in Shetland serves as an example of this geological feature, illustrating the connection formed between the mainland and an island.
