Which process explains saltwater lake formation near coasts?

💡 Explanation

Longshore drift deposits sediment because wave action reduces energy, therefore forming spits and barrier islands which enclose a body of water; this creates coastal lagoons or saltwater lakes rather than glaciation or tectonic action happening near the shoreline.
