The most common process that supplies sand to a coast is primarily the result of wave action. Waves orchestrate the movement of sand and sediment along shorelines through a process called longshore drift as they approach the shore, breaking down rocks along the way and redistributing the sand along the coast.

While other processes such as cliff erosion also contribute to the supply of sand, the continuous action of waves is the dominant mechanism that ensures a steady replenishment of sand to coastal areas. Streams and wind can transport sand as well, but they do not directly contribute to coastal sand supply to the same extent as wave activity.

Final Answer

Waves are the most common process that supplies sand to a coast.
