A 'sand bar'.

size of sand grains
Waves approach a shore obliquely (at an angle) due to the effects or the tides, currents the coriolis effect etc. and then retreat due to gravity straight. A good analogue is to roll a marble up a slope at an angle; it will fall more linearly on its return. Hope this helps.

How sand and other materials are carried parallel to the shore by the waves. The waves approach the beach at an angle.Longshore drift is the movement of sediment along the coastline.Longshore drift is the transport of erosion sands along a shoreline by the current flowing along it.
sand ridges that rise slightly above the surface of the sea and run roughly parallel to the shore, from which it is separated by a lagoon.
Long-shore drift occurs in two ways: the wave driven movement of sand along the exposed beach and the current-driven movement of sand in the surf zone just offshore.
Sand Spit: A sand spit is an elongated line of sand that usually extends parallel to shore. Barrier Islands: Barrier Islands are long,narrow coastal island.
It is a shore made up of sand
