What structure is most likely to be created by the deposition of sediment from littoral drift?

The structure most likely created by the deposition of sediment from littoral drift is a spit. Littoral drift refers to the movement of sediment along the coastline due to the action of waves and currents. When this sediment is deposited in a way that extends into a body of water, it can form a narrow landform known as a spit.

Spits are characterized by their elongated shape, projecting from the shore into a bay or sea, and typically form where the prevailing currents and wave direction create conditions favorable for sediment accumulation. Over time, as sediment continues to be deposited, the spit builds outwards, often creating unique ecological zones and impacting local marine environments.

In contrast, other options such as estuaries, fiords, and cliffs involve different geological processes. Estuaries are formed at the mouths of rivers where freshwater meets saltwater, creating a unique habitat, while fiords are deep, narrow inlets formed by glacial activity. Cliffs are usually the result of erosion and geological uplift rather than deposition.
