If a ridge of material links an island with the mainland, this ridge is called a tombolo. Drift aligned coasts: beaches are produced where waves break at an angle to the coast. A spit is a stretch of sand or shingle extending from the mainland out to sea. These depend on the size of sediment: Suspension - Fine particles of silt hang in the water. This causes material to be deposited in a long thin strip that is not attached to the coast and is known as a spit.
