Final answer:
Longshore drift is the process of sediment transportation along the coast, influenced by longshore currents.
Step-by-step explanation:
Longshore drift is the process by which sediment is transported along the coast. It occurs when waves approach the shoreline at an angle, causing sediment to move parallel to the shore. The movement of sediment is influenced by longshore currents, which are the dominant currents in the nearshore zone that run parallel to the shore.
