GCSE Geography Revision - Made Easy!
All you need to know about Spits and Tombolos on the Coast!
When the sea transports material, such as sand, silt and rocks, it is eventually deposited somewhere other than where it was picked up along the coastline. This process is called longshore drift. Longshore drift is caused by prevailing winds making the swash and backwashes of waves move in a zig-zag formation, edging beach material along a coastline.
Longshore drift can then lead to the deposition of material in a way that juts out from a headland or coastline, along a rive mouth or potentially along a bay. These depositional landforms are attactched to the mainland at one end, and stretch out a long way either unattactched, or attached to an island. These landforms are called spits and tombolos.
