It moves it in a zig zag motion. The waves go up the beach in an angle, so when the waves breaks at an angled the pebbles/materials are carried up the beach in the direction of a wave (swash) and when the wave returns to see dragging some materials back with it called a backwash.
hope this helps
The waves churn up the sand and the longshore current carries it along the beach. And thats how sand moves and a beach!! Remember to always copy off Google kids!! Lol joking xD im in 6th grade sooo yeah peace!! Hope this helped at all.
Longshore drift creates sandbars (other wise know as spits) by transporting and depositing material at an angle along the coast. when the headland leaves a gap of sea inbetween two headlands. a spit forms untill it reaches the second headland then it is a bar the sea behind the bar is called a lagoon.
The waves churn up the sand and the longshore currant carries it along the beach.
The force from the waves ( caused by the moon) push the sand therefore moving the sand across the beach. :) hope this helps sorry if it doesn't :\
put the answer!~!
beach drift and longshore current
Longshore currents shift sand and move water parallel to the shoreline

Longshore drift is the process that moves sand and other sediments along a shoreline. It is also referred to as longshore transport or littoral drift.
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.
Erosion
The smallest particles on a beach are found closest to the shoreline and many of those small grains of sand are carried into the sea with the waves. The coarser grains of sand are what actually builds up the beach.
the waves
The wind.

When the tide comes in or goes out, the water replaces the sand there, making the animal's presence practially unknown.
In temperate climates the sand on the beach comes from the rocks eroded form the shoreline by the waves. In tropical climates the sand is mainly composed of broken up shells from sea creatures (a coral sand beach).
