4. Longshore drift transports material along the coast Transport and deposition occurs in roughly the same direction to form a SPIT, ignoring the change in direction of the coastline The curved end represents periods of change in the direction of longshore drift, as winds have changed direction Sediment (mud or silt) is transported down the river and deposited in the calm waters behind the spit Fresh water marsh is formed here as the build up of sediment is so great that it rises above the water level even in high tide storm conditions. Sometimes this is drained and used for farm land Some of the sediment forms mudflats which are low lying and covered with sea water every high tide. Sometimes the build up of sediment is such that it is only occasionally covered in sea (salt) water. This forms boggy areas of salt marsh

6. Occasionally strong winds blow from a different direction. Some material is then pushed inland causing the end of the spit to curve. This can happen on a number of occasions over time, producing a spit with several hooked ends.
