What is a sandbar connected to a curving shoreline?

A sandbar connected to a curving shoreline is a natural formation of sand that accumulates in shallow water, often shaped by the action of waves and currents. It typically runs parallel to the shore and can create a sheltered area between the bar and the land, which is beneficial for marine life. These formations can shift over time due to changes in water flow and sediment deposition. Sandbars are important for coastal ecosystems and can influence local navigation and beach dynamics.
