The video tutorial explains the formation of river deltas, barrier islands, and salt marshes. River deltas form when sediment carried by rivers is deposited as the river slows upon entering a larger body of water. Barrier islands are long, narrow islands formed by sediment transported by waves and currents, providing protection from erosion. Salt marshes are coastal wetlands that offer habitats for wildlife and act as natural water filtration systems. The video highlights the ecological importance of these landforms.
