beaches absorb waves and backwash in some areas of the coast
longshore currents for example ,often deposit sand along shorelines,the sand builds up to form sandbars
Longshore currents
effect. longshore drift is the combined effect of sediments moved by longshore currents and and beach drift. longshore currents are ocean currents that flow parallel to the coast while beach drift is the resultant zigzag movement along the beach.
what is a current

what is a current
Longshore currents are driven by the angle at which waves approach the shore. When waves hit the shore head-on, rather than at an angle, there is no net transport of water along the shoreline to generate a longshore current. The wave energy is dissipated directly onto the shore, preventing the development of a longshore current.
Longshore Currents transport most sediment along the shore of beaches, according to my science book. .

Longshore drift is the effect of longshore current because the water moves a certain way and causes the sand to take shape.

These currents are called LongShore or Feeder Currents.
