longshore drift
Long ridges of sand parallel to the shore are known as sandbars. They are formed by the action of waves and currents depositing sand in shallow areas along the coast. Sandbars can shift and change shape over time due to the movement of water.
A ridge of sand that runs parallel to the shore is called a sandbar. Sandbars are typically submerged or partially exposed at high tide and can be an important habitat for marine life.

Sand gets transported along a beach primarily through longshore drift, where waves approach the shore at an angle and carry sediment parallel to the coastline. Additionally, tides and currents can also contribute to the movement of sand along a beach.

Longshore currents transport sediment along the coastline parallel to the shore. These currents are driven by the waves hitting the coast at an angle, causing sediment to move in a zig-zag pattern along the shoreline.
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.

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.
