Concept:Spits are coastal landforms created when moving beach material is deposited into the sea.
Explanation:Waves usually hit the coast at an angle.
This causes long shore drift, which carries sand and shingle along the beach.
When the coastline changes direction, such as at a river mouth or bay entrance, the material stops moving along the shore.
Wave deposition then builds this material outwards into the sea as a narrow ridge.
This deposited ridge of sand or shingle is called a spit.
Therefore, long shore drift supplies the sediment and wave deposition forms the spit.
Answer:C. Long shore drift and wave depositions
