The direction of longshore drift is typically parallel to the coastline. It moves sediment and materials along the shoreline in a zigzag pattern due to the angle of incoming waves.
Longshore drift and longshore currents can produce landforms such as spits, tombolos, barrier islands, and sand dunes. These landforms are typically found along coasts with significant wave action and sediment movement.
long-shore drift
Longshore drift is the process of sediment moving along a beach due to wave action. It is driven by the longshore current, which is a current that flows parallel to the shoreline. Therefore, longshore drift is the result or effect of a longshore current.
A drumlin is a long, narrow hill formed by glacial drift. Drumlins are typically elongated in the direction of glacier movement and have a smoothed, rounded shape.
Long shore currents form when waves approach the shoreline at an angle, causing the water and sediment to move parallel to the shore. This movement is a result of the wave's swash and backwash, creating a current that flows along the coastline. Long shore currents are influenced by wave direction, wave energy, and the shape of the coastline.
Spits are formed when longshore drift travels past a point where the dominant drift direction and shoreline do not veer in the same direction.

long-shore drift
A spit is formed due to the process of the long shore drift, the waves approach the beach in the direction of the prevailing winds, this causes the sediment to be pushed up the beach at an angle.

throught the processes of long shore drift and transportation & deposition
Because it does okay! Well i need the answer to this as well :(
Shore drift consists of the transport of sediments (generally sand but may also consist of coarser sediments such as gravels) along a coast at an angle to the shoreline, which is dependent on prevailing wind direction, swash and backwash [1] This process occurs in the littoral zone, and in or within close proximity to the surf zone. The process is also known as shore transport
Short shore drift consists of the transportation of sediment (clay, silt, sand and shingle) along a coast at an angle to the shoreline, which is dependent on prevailing wind direction, swash and backwash. This process occurs in the littoral zone, and in or close to the surf zone. The process is also known as short shore transport or littoral drift.Short shore drift is influenced by numerous aspects of the coastal system, with processes that occur within the surf zone largely influencing the deposition and erosion of sediments. Short shore currents can generate oblique breaking waves which result in short shore transport.Short shore drift can generally be defined in terms of the systems within the surf zone as seen in figure 1. This figure shows that sediment transport along the shore and surf zone is influenced by the swash (occurs in the direction of prevailing wind), which moves the pebble up the beach at the angle of the waves, and moves the pebble back down the beach due to the influence of gravity.Short shore drift affects numerous sediment sizes as it works in slightly different ways depending on the sediment (e.g. the difference in long shore drift of sediments from a sandy beach to that of sediments from a shingle beach). Sand is largely affected by the oscillatory force of breaking waves, the motion of sediment due to the impact of breaking waves and bed shear from long shore current. Whereas because shingle beaches are much steeper than sandy ones, plunging breakers are more likely to form, causing the majority of long shore transport to occur in the swash zone, due to a lack of surf zone.
The process of longshore drift is waves hit up against the sand and the sand grains are taken by the waves back into the sea and back to shore again, this is called swash ans backwash.
