Barrier islands form parallel to the shore due to longshore currents transporting sediments along the coast. These currents deposit sediment further away from the mainland, leading to the gradual formation of barrier islands. Over time, the islands stabilize and provide protection to the mainland from waves and storms.
Barrier islands mainly form as a result of wave and tidal action, which transport sediments along the coast and deposit them into long, narrow strips parallel to the shore. These islands act as natural buffers, protecting the mainland from erosion and storm damage.
Longshore currents move sand along the coast by carrying it parallel to the shoreline. As waves approach the shore at an angle, they generate a current that moves sediments in a zigzag pattern. This process helps to redistribute sand along the coastline.
accumulated sediments on the bottom of the river
Glaciers are the agent of erosion that deposit irregular mounds of unsorted sediment with parallel scratches on rounded particles. This type of deposit is called a moraine, which is formed as the glacier moves and carries a mixture of different-sized sediments that get deposited when the glacier melts.
longshore drift
Drift and/or till.

a place where a river meets the shore
Water can deposit sediment such as sand, silt, and clay. Wind can deposit smaller particles like sand and dust. Melting glaciers can deposit a mixture of rocks, sediments, and debris known as moraines.
When sediments deposit in lakes or oceans, they typically settle in layers on the bottom of the body of water. Over time, these layers can build up and form sedimentary rock.
It forms a beach.
