Physical Features of Louisiana
Louisiana is defined by its low-lying coastal plains, extensive wetlands, and river-dominated landscape. Much of the state is shaped by the Mississippi River, which creates fertile alluvial plains and a vast delta in the southeast. Swamps, bayous, and marshes cover large areas, especially near the Gulf of Mexico coastline. The northern part of the state features slightly higher ground with rolling hills and forests, but overall Louisiana remains one of the flattest states, with water playing a central role in its geography.
