Longshore drift transports material along the coastline Spits formed in shallow and sheltered water when there is a change in the direction of the coastline Deposition occurs resulting in the accumulation of sand and shingle The material initially deposited is the largest material, dropped due to the reduction in energy 4. On deposition-dominant coasts, the coastal sediments are still being eroded from some areas and deposited in others. Who wrote the music and lyrics for Kinky Boots?

A further depositional coastal landform is a tombolo, the name given to a spit that joins an island to the mainland.

Sometimes, the island at the end of the bar, or spit, is large enough that it supports commercial or residential activity. For this to occur, waves must have limited energy, so beaches often form in sheltered areas like bays . The shallower waters that occur between an island and the mainland are the loci of such features because sandbars form there. They form when sediment is transported on and off a beach. Sand grains travel southward down the coast, while finer particles of sediment are carried and deposited further out to sea. and pebbles. On the map, sketch where you would expect the following to form: What conditions might lead to the formation of barrier islands in this area?
