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.

They don't. Groynes inhibit longshore drift. Longshore drift occurs when currents develop parallel to a shoreline as a result of wave action, carrying sediment with them. Groynes catch sediment and interfere with these currents. Continental drift, a part of plate tectonics, is a completely unrelated process.
It is mainly evidence for constructive waves and the results of this construction are spits and bars.
Sand is gradually carried down the beach by Longshore Drift.
Over a period of time, whole beaches can be washed away along the coast, sometimes in the space of a single year. Some holiday resorts have to pour or pump sand on to their beaches to replace the material carried away by long-shore drift. Harbors can be completely blocked by the sand ans shingle carried away by long-shore drift. I hope this answer was quite helpful or in some way giving and answer to you question.

The erection of sturdy, wooden barriers, set at right-angles to the coastline, known as Groynes (UK) help to slow down or prevent longshore drift.
Spits are formed when longshore drift travels past a point where the dominant drift direction and shoreline do not veer in the same direction.

longshore drift
Angled waves create a current that runs parallel to the coatline. As waves repeatedly hit the beach, some of the beach sediment moves down the beach with the current.

throught the processes of long shore drift and transportation & deposition
thats not a question.

How about this: continents drift. That's about as short as I can make it.
